Barcelona 6-1 PSG, Borussia Dortmund 4-0 Benfica: Uefa Champions League last 16 - as it happened

I may need a lie down after that. I've covered both of these ties and seen 11 goals and suffered several minor tremors in the old ticker. How Barcelona came back not once, but twice I haven't a clue. Luis Enrique's side looked down and out, and now they must be considered favourites for this competition.

Well that is about all we have time for on this remarkable night of Champions League football. We're back tomorrow with the rather incidental Europa League though there is Premier League interest in the form of Manchester United. But until then, goodbye. Get some rest.

Luis Enrique is leaving Barcelona at the end of the season - is he having second thoughts after that late drama?

The moment Sergi Roberto created history at the Nou Camp.

Full time: Manchester City 0-0 Stoke City

What has just happened?!?!? Barcelona have just created history; the first team to overturn a four-goal first leg deficit and go through in the Champions League. PSG looked done and dusted, both at 4-0 up after the first leg, and then when Edinson Cavani smashed home. Barca scored twice in the final two minutes of normal time, before in the fifth minute of added-on time Sergi Roberto poked home the winner.

Full time: Barcelona 6-1 PSG

GOAL! Barelona 6-1 PSG (Sergi Roberto)

Remember where you were. Sergi Roberto toe-pokes Barcelona into the Champions League quarter-finals as Neymar's cross floats into space and Trapp is beaten. The most amazing comeback in European club football history.

Free-kick in the penultimate minute. Ter Stegen goes forward.....

Five added minutes for Barcelona to produce the most unlikely comeback, and one for the ages if they can do it. PSG holding their own at the moment.

GOAL! Barcelona 5-1 PSG (Neymar)

Marquinhos' foul gives Barcelona the chance to get another, and Neymar makes no mistake. Cavani's goal is sending PSG through as things stand. Into stoppage time....

PENALTY TO BARCELONA

GOAL! Barcelona 4-1 PSG (Neymar)

Barcelona need a goal a minute but they get one via a classic free-kick from Neymar which beats Trapp, who doesn't even dive such is the accuracy of the strike.

Substitute Angel di Maria should put the icing on the cake for PSG but skews his effort wide while one-on-one with Ter Stegen. Nevertheless, Barcelona need a minor miracle from here.

GOAL! Borussia Dortmund 4-0 Benfica (Pierre-Emerick Aubameyang)

David Silva drives wide for City in what is the best chance either side have created in the opening 72 minutes. I wonder if we'll have another anywhere near as decent.

Man City continue to be frustrated at the Etihad. Sergio Aguero has barely had a kick and he has his best chance of the night, a near-post toe-poke towards goal which roles wide. Stoke survive.

Deep inside the final 20 minutes at the Nou Camp and it would be not exaggeration to say that the Cavani goal has deflated the hosts. Messi breaks into the box and shoots wide, as another opportunity comes and goes. They need some of the fortune of the first half to stand any chance here.

Edinson Cavani thrashes PSG to the brink of the quarter-finals.

GOAL! Barcelona 3-1 PSG (Edinson Cavani)

Game-changer and perhaps the deciding goal of the tie. Rakitic is caught out from a long ball and as Kurzawa wins it, it falls to Cavani who lashes the ball into the roof of the net. From needing one to get extra time, Barcelona need three more to go through.

Back underway at the Etihad Stadium as Manchester City and Stoke City resume in their Premier League clash. Goalless at the moment and as things stand, slipping into the background as far as the football headlines tonight.

GOAL! Borussia Dortmund 3-0 Benfica (Pierre-Emerick Aubameyang)

Barcelona celebrate the second goal as thy look to create history.

AGAINST THE POST! The tension is palpable around the Nou Camp and PSG could have put the tie to bed as Meunier's cross is turned onto the woodwork by Cavani. What a chance for PSG, who have been woeful in this opening 52 minutes.

GOAL! Barcelona 3-0 PSG (Lionel Messi)

The fortune remains with Barcelona as they get a third. Neymar was mighty fortunate to get the penalty, not because it should not have been awarded but due to Meunier falling into the Brazilian. Messi made no mistake from the spot, driving past Ter Stegen.

Drama at the Nou Camp as Meunier slips over and takes out Neymar. The referee doesn't give it initially, but eventually points to the spot. Messi over it.....

PENALTY TO BARCELONA

Back underway in Barcelona and Dortmund. Can the comebacks be completed?

Half time: Manchester City 0-0 Stoke

Half time: Barcelona 2-0 PSG

Luis Enrique's handed a lifeline in this tie as they aim to create history. Luis Suarez headed home after three minutes before Layvin Kurzawa's own goal handed Barcelona hope, with PSG contributing to their own downfall. In between the hosts have not been all that impressive, but any improvement will make the French visitors sweat.

Half time: Borussia Dortmund 1-0 Benfica

Here is that calamitous second goal for Barcelona. Awful goal to concede from a PSG point of view.

Yellow card as Gerard Pique fouls Cavani, but it is not for the already-cautioned Barcelona defender. Cavani demands he be reprimanded and he finds himself into the referee's notebook.

GOAL! Barcelona 2-0 PSG

Job half done and what a catastrophe at the back for PSG. Iniesta keeps the attack alive with a backheel and Kurzawa takes an almighty swing at the ball and it bounces into the corner. Barcelona have offered nothing in the last 10 minutes or so, but they have a lifeline in this tie.

Lee Grant called into action, forced into a low save to keep out Aleksandar Kolarov's free-kick from the left. City starting to improve but failing to discover the slickness from the win over Sunderland.

Sergio Busquets booked for dissent and he will miss the first leg of the quarter-final, if Barcelona make it. Long way to go until that becomes a factor, however.

Trapp saves from a poor Suarez effort from the angle, after being played in by Messi. That was never going to threaten the goal.

Rafinha all over the shop on the Barcelona right, trying to provide balance but failing with a lack of conviction. PSG have weathered the early storm and look, dare I say it, comfortable.

Pierre-Emerick Aubameyang scores the opener for Dortmund to draw them level in the tie.

Sums up the first 30 minutes nicely, as Ter Stegen saves from Lucas.

Stoke still probably at City and they go close again when Ramadan turns Otamendi and it takes a hooked Sagna clearance after a fortunate deflection to clear the danger.

One for those who accuse Premier League players over being over-pampered.

Not much in the way of chances at the Etihad, the only one coming for visitors Stoke who last won here in 2014. Erik Pieters' cross was met by Diouf, who diverted the ball goalwards but saw Caballero claw the ball away.

PSG happy to soak up the pressure and break on Barcelona, the problem being that they're not seeing much of the ball. A quarter of the game gone and a quarter of the job is done for Barca. Three more required.

Neymar may not have had the best of seasons - he played at the Olympics in the summer - but he almost halves the deficit as the Brazilian blasts goalwards but sees the effort fly wide.

Underway at the Etihad Stadium where Manchester City are taking on Stoke. Pep Guardiola's men can go second tonight with a win, while Stoke will hope to cement a top half spot. Updates as the evening progresses.

Early delight for Barcelona as Luis Suarez gives them the lead.

Julian Draxler wants a PSG penalty and you can see why. He crosses from the left and as Mascherano blocks the ball, his trailing arm puts the ball behind. The referee, Deniz Aytekin, is unmoved.

You know things are going well when Javier Mascherano feels the need to shoot from range. The Argentina collects the ball from a half-cleared corner, but shanks his volley wide.

For those that missed it, here is how Luis Suarez gave Barcelona the lead on the night.

GOAL! Barcelona 1-0 PSG

Amazing stuff and the perfect opening for Barcelona. Kevin Trapp is flapping all over the place and he allows Suarez to steal in and head the bouncing back overt he line, despite the best efforts of Marquinhos.

GOAL! Borussia Dortmund 1-0 Benfica [Pierre-Emerick Aubameyang]

Big goal too in Dortmund, not that you'd know it. Gabon international Aubameyang fires the hosts level in the tie.

Underway in Barcelona and Dortmund. The Premier League match at the Etihad Stadium begins at 8pm.

Players in the tunnel at the Nou Camp. Barcelona can't do it, can they?

Kick-off is fast approaching across Europe, including in Manchester for our one and only Premier league game. Barcelona vs PSG is very much our focus, but we'll have news of all the goals as they go in Germany where Dortmund are hosting Benfica, and Manchester where City face Stoke.

What approach do PSG adopt tonight. Having twice been dumped out of the competition by Barcelona in recent seasons, the mountain to climb tonight is as psychological as it is physical. But with a 4-0 lead can they attack with reckless abandon, or do they sit off and try and frustrate their illustrious hosts.

You'll notice the irregular occurrence of a Premier League game clashing with a Uefa European game tonight. The dynamic is banned by the continent's governing body, and they are unhappy with the prospect of Man City hosting Stoke, which could see them withdraw payments to England's top division. Here is the Premier League's response.....

Messi and co. stood like statues three weeks ago, but can they prove elusive tonight?

The manner in which Barcelona fell apart three weeks ago when they lost 4-0 to PSG in the first leg, meant that Luis Enrique's future, not least progress in the competition, appeared bleak.

But since the Spaniard confirmed his departure Barcelona have been in a rich vein of form and having scored 11 times in their last two games they have shown they have the powers of resolve to stage an unlikely comeback. No side has recovered from four goals down to win a two-legged tie in the competition, but can a forward line of Messi, Suarez and Neymar break another record?

If you're crazing a bit of domestic action amid the European flamboyance, then never fear because there is a dose of Premier League action in the form of Man City vs Stoke. Below are the all-important teams....

Teams from the second of two Champions League last 16 second legs on the way. Dortmund host Benfica trailing 1-0 from the first game.

Even with a 4-0 lead, you don't envy the task facing PSG tonight.

After Arsenal suffered their worst ever Champions League knock-out stage defeat to Bayern Munich, 10-2 after another 5-1 loss at The Emirates, a word on a record Barcelona will be hoping to avoid tonight. Barca's worst two-legged loss came just four years ago when Bayern won 7-0 on aggregate, so another record could go at the Nou Camp if PSG cash in like they did in the first leg.

Just one change for Unai Emery's French champions, with Presnel Kimpembe replaced by captain Thiago Silva. Otherwise, it is the same team which embarrassed Barca in the first leg, looking to complete the job.

PSG: Trapp; Meunier, Marquinhos, Silva (c), Kurzawa; Rabiot, Verratti, Matuidi; Lucas, Cavani, Draxler

Couple of changes for Barcelona from the first leg humiliation at the hands of PSG three weeks ago. Rafinha, Rakitic and Mascherano come back in, with Sergi Roberto, Jordi Alba and Andre Gomes dropping out.

And ahead of schedule, the Barcelona team is in....

Teams should be with us in around 20 minutes, but how do we expect both sides to line up? Starting with Barcelona vs PSG.....

Jeremy Mathieu and Aleix Vidal are missing for Barcelona with long term injuries, otherwise Luis Enrique has a fully-fit squad to choose from.

Adrien Rabiot, Angel Di Maria and Thiago Motta are all available for PSG after respective injuries.

Luis Enrique may have decided to take his leave from Barcelona at the end of the season, but the Spaniard is far from done in the Nou Camp hotseat. The Spaniard has won eight trophies from 10 competitions with Barca, and he won't want that record to be hindered by an early exit from the Champions League.

The 4-0 defeat to PSG three weeks ago may have been the beginning of the end for Enrique but the freedom the Catalans have played without since announcing his decision to step down, does give them renewed hope tonight. No side has clawed back a four-goal first leg deficit in the Champions League - but if anyone can an attack of Messi, Neymar and Suarez will certainly give it a fair crack.

In the other European tie, Dortmund will host Benfica hoping to overturn a one-goal lead from the first leg in Portugal. And if that wasn't enough, we'll have updates from the Premier League where Manchester City can go second and eight points behind leaders Chelsea if they beat former manager Mark Hughes' Stoke City.
