Well what a stunning evening of Champions League football. The knives are out for Arsene Wenger and Arsenal after they are embarrassed by Bayern Munich, while Real Madrid overcome Napoli after going behind.
That brings an end to our live coverage, but we'll have all the reaction from both games over the next 24 hours. The fall out from the events at the Allianz Arena is sure to reverberate around football. Until next time, goodbye.
Full time: Bayern Munich 5-1 Arsenal, Real Madrid 3-1 Napoli
This has been an absolute humiliation for Arsenal. I can't imagine Arsene Wenger can survive this.
GOAL! Bayern Munich 5-1 Arsenal (Thomas Muller)
Goodnight Arsenal, and perhaps Arsene Wenger as well. Thomas Muller has just come on and he cuts inside and smashes in. The humiliation is complete.
Philippe Lahm out of the second leg as he fouls Alex Oxlade-Chamberlain. Another goal for Arsenal would very much keep this tie alive. Can they get it though?
Napoli believe they have a goal back but they are denied by the offside flag. Callejon, formerly of Real Madrid, slides in at the back post bu the assistant chalks off a goal on his return to the Bernabeu.
Real also threatening to put Napoli out of sight and Toni Kroos carves open the visitors with a delicious through ball, but Reina comes out to save from James.
Thiago Alcantara drives goalwards to further extend Bayern's lead.
Ospina pushes out Vidal's strike as Bayern look to repeat the 5-1 scoreline they inflicted upon Arsenal last season.
How most Arsenal fans are feeling...
GOAL! Bayern Munich 4-1 Arsenal (Thiago Alcantara)
This looking like a bridge too far for Arsenal already. Thiago shoots from 20 yards and via a deflection off Xhaka it goes beyond Ospina. Three goals in nine minutes since Laurent Koscielny went off.
Toni Kroos rejoices after putting Real ahead for the first time.
GOAL! Bayern Munich 3-1 Arsenal (Thiago Alcantara)
Superb team goal and have Bayern extinguished Arsenal's hopes here? Lewandowski flicks the ball round the corner and Alcantara is all along and he strokes past Ospina. Suddenly, Arsenal's future in this competition looks precarious once again.
GOAL! Real Madrid 3-1 Napoli (Casemiro)
Oh my, I've gone too early with the goal of the night prize. A Real attack breaks down but Casemiro lashes the loose ball, on the volley, into the corner from 25 yards. A truly stunning strike.
GOAL! Bayern Munich 2-1 Arsenal (Robert Lewandowski)
Arsenal concede just minutes after losing their captain. Philippe Lahm crosses from the right and Lewandowski leaps highest and powers a header beyond Ospina.
Injury for Arsenal captain Laurent Koscielny as he is replaced by Gabriel less than five minutes into the second half. Big blow for the Gunners, with Sutton United to come next week.
GOAL! Real Madrid 2-1 Napoli (Toni Kroos)
Sloppy start from the hosts is replaced by them taking the lead. Ronaldo gets to the byline and pulls it back for Kroos, who sweeps the ball back past Reina, who looked blinded by his own defence. Fine goal.
Players out and we're back underway in the second halves in Munich and Madrid. More of the same, please.
Half time: Real Madrid 1-1 Napoli
Also half time at the Bernabeu where Real Madrid have dominated but Napoli will be the happier. Lorenzo Insigne netted the goal of the night to put the Italians ahead, before Karim Benzema's headed equaliser. The hosts should be out in front by now, but Pepe Reina has been in inspired form on his return to Spain.
Half time: Bayern Munich 1-1 Arsenal
This is turning into a classic Arsene Wenger performance from Arsenal. So much criticism in recent weeks, but they remind everyone of their ability just at the right time. The Gunners have held their own, had the better of the chances and are deservedly level. Alexis Sanchez opened the scoring, after Arjen Robben's early stunner. Just what the doctor ordered.
Real Madrid pushing hard and should be ahead. Ronaldo plays the ball round the corner and Benzema nips in, but the pressure from Reina is enough to see the effort go off target.
Bayern go close to re-taking the lead. Alaba crosses and Lewandowski leaps, but miss-times the header.
What a chance for Arsenal! They build well through Sanchez again, and when Oxlade-Chamberlain pulls his cross back to the edge of the area Xhaka hits it first time but straight at Neuer.
Alexis Sanchez delivers a crucial equaliser for Arsenal.
