Champions League scores
Bayern Munich 4-0 Besiktas
Chelsea 1-1 Barcelona
Well that brings an end to our live coverage of this Champions League night.
We'll be back tomorrow with coverage of Sevilla vs Manchester United, but until then goodbye.
Full time: Bayern Munich 5-0 Besiktas
Way to easy for Bayern. Once Vida was sent off it was one-way traffic. Two each for Muller and Lewandowski, while Kingsley Coman got the other.
Full time: Chelsea 1-1 Barcelona
Advantage to the La Liga leaders after Lionel Messi cancels out Willian's effort from range. Chelsea did have the lead but they gave it away via Christensen's pass across his own penalty area, which led to Messi hammering home.
A very competitive tie however and a fascinating second leg awaits in three weeks time.
Iniesta off and Andre Gomes on for the final two minutes of added time. Barcelona closing this one down.
Three minutes added on at Stamford Bridge. Will we get a winner?
GOAL! Bayern Munich 5-0 Besiktas (Robert Lewandowski)
The garnish on an easy win for the Bavarians. Muller plays the ball across and Lewandowski escapes his marker and plants the ball into an empty net.
Alvaro Morata is also on for Chelsea but his only involvement thus far has been to be booked for descent, protesting that the hosts should have been awarded a corner.
The streak is broken.
Danny Drinkwater on for Cesc Fabregas for Chelsea. Six minutes to go.
Lionel Messi steers Barcelona level.
GOAL! Bayern Munich 4-0 Besiktas (Robert Lewandowski)
The Poland striker has hit goal his display has deserved. Hummels shoots from 30 yards and while his shot is kept out Lewandowski slams home on the follow-up.
What did I say?
GOAL! Chelsea 1-1 Barcelona (Lionel Messi)
Andreas Christensen hang your head. The Dane passes the ball across his own penalty area - you learn not to do that as a kid - and Barca take full advantage. Iniesta nips in and pulls the ball back for Messi, who wrong-foots Courtois and finds the net. Tie turned on its head.
Willian thunders Chelsea into a second half lead.
This was Barcelona's approach to marking Willian before he opened the scoring, having hit the post twice in the first half. Not smart.
GOAL! Bayern Munich 3-0 Besiktas (Thomas Muller)
Jupp Heynckes' side are heading for the quarter-finals at this rate. Muller gets his second after touching in Kimmich's cross. Still a quarter of the game remaining.
Aleix Vidal on for Paulinho, who has struggled to be honest. Barcelona going in search of an away goal.
GOAL! Chelsea 1-0 Barcelona (Willian)
Third time lucky for the Brazilian. Willian collects the ball on the edge of the box, shifts the ball to the side of Busquets and drives the ball past Ter Stegen - who was blindsided.
Luis Suarez has been a peripheral figure tonight.
Alvaro Morata warming up as Barcelona's dominance in this half continues. Just a moment ago Hazard was fed the ball with his back to goal in the box, and he was easily shrugged off the ball by Pique. How they could do with a physical presence in attack.
GOAL! Bayern Munich 2-0 Besiktas (Kingsley Coman)
Bayern have dominated the start of the second period and they double their lead as Lewandowski - who has just hit the post from a free-kick - pulls the ball back and Coman arrives on cue to slide into the corner.
Cesar Azpilicueta shows his importance to the Chelsea cause by forcing Iniesta down a blind ally and winning a throw-in for the hosts.
The experienced World Cup winner gets on the ball again but his left-footed effort is well wide.
Players out for the second halves in west London and Bavaria. No changes in either game as they resume.
