Four minutes of injury time signalled. Can Arsenal hang on?

Incredible scenes at Bradford as James Hanson heads Bradford into a 2-1 lead.

Nervy, nervy times for Arsenal as Besikltas attack and that could be their chance.

Gokhan Tore's cross at the far post is close to picking out Demba Ba but the Senegal striker fails to make proper contact and the ball goes wide. Manger Slaven Bilic was on his feet before having his head in his hands.

Adam Johnson doubles Sunderland's lead with a right footed shot from the centre of the penalty area to the bottom left corner after a pass from Jozy Altidore.

Jon Walters has scored two, and he makes the third with a cross which Peter Crouch gobbles up. Textbook header.

Leeds were only ahead for two minutes at Bradford before Billy Knott sends the home fans into delight with a right-footed shot from outside the box that goes into the top right corner of the net.

"It's interesting that since Arsenal have gone down to 10 men, it has galvanised the team and the fans together. It's an excellent atmosphere in here tonight."

Arsenal goalkeeper Wojciech Szczesny is booked for time wasting. Arsenal are working hard to keep Besiktas at bay and have a free-kick inside the Turk's half. Into the corner it goes......

Leeds United have been down to 10 men since the 30th minute, but David Hockaday's side take the lead in the West Yorkshire derby as Matt Smith heads them into a 1-0 lead.

The cross came from David Norris and Smith got his first goal of the season.

We are into the last five minutes. A goal now for Besiktas and Arsenal are surely out?

"Debuchy actually gets to the ball, but I think he has an arm on the player.

"But just ahead of that moment, Oxlade-Chamberlain had a chance to finish this match.

"Now this tie is wide open. Arsenal down to ten men."

Henry in the Emirates: Is this referee watching the same game? He has been awful all game. Awful display.

Ben in Cobham: A Besiktas equaliser would do Arsenal a favour as they would then be in a competition they could actually go on to win, rather than make up the numbers .

Adam in Darlington: Anyone who thinks Arsenal might be better not being in Europe, ask any Man United fan if they think the same.

There is no parking the bus from an adventurous 10-man Arsenal. Attack is obviously seen the best form of defence as the match swings from end-to-end. Both sides look capable of scoring.

Besiktas are pushing for that away goal now. Arsene Wenger is looking a little twitchy on the substitutes bench and who can blame him? Seven minutes to go.

This could be a horrible last 11 minutes for Arsenal. Although they are still pushing for the second and Atiba Hutchinson is booked for lunging at Alexis Sanchez after some brilliant skill from the Chilean. Free-kick to Arsenal 30 yards out.....

Sanchez is inches from converting a whipped-in free-kick but can't make proper contact.

Sunderland get the breakthrough at St Andrew's as Jordi Gomez puts the Premier League side ahead.

The goal comes from Adam Johnson's pass, which finds Gomez 25 yards out and he drills a low effort past Birmingham goalkeeper Colin Doyle. But Blues' boss Lee Clark is furious, arguing the ball had gone out in the build-up to the goal.

Shock alert! League Two side Burton Albion take the lead against top-flight opposition and it's a beauty too, Adam McGurk curling a free-kick home from 20 yards.

Just seconds after Arsenal squander a golden opportunity through Alex Oxlade-Chamberlain to take the lead, they are down to 10 men when Mathieu Debuchy receives his second yellow card for tugging back a Besiktas player.

Chaos here as Calum Chambers is also booked for coming on too early as he replaces Mesut Ozil.

Arsenal should be 2-0 up though as Oxlade Chamberlain had his shot at the far post blocked before Debuchy's sending off. He should score.

Arsenal could live to regret that. The break quickly and have three players against two. Alexis Sanchez dallies and dallies before squaring to Santi Cazorla, who misses from close range.

Elsewhere in the Champions League, Athletic Bilbao look as they are into the group stages, leading Napoli 3-1 on the night and 4-2 on aggregate. Bayer Leverkusen are beating Copenhagen 7-2 on aggregate.
