Gabriel is having a solid game. He is reading situations very well.
Sane is trying to make the runs to get in behind but Gabriel is winning that battle so far.
Arsenal 1-1 Manchester City
The TV cameras are focusing on Willy Caballero on the City bench. Will Pep Guardiola bring him on for penalties, if we get that far?
You could leave Bravo on and put him in midfield.
Arsenal 1-1 Manchester City
The 90 minutes have been full of chances for City including Yaya Toure and Fernandinho hitting the woodwork twice. Take a look for yourself.
Arsenal 1-1 Manchester City
The pattern continues. City on the ball, Arsenal well placed to soak it up and counter.

Away we go.

Arsenal 1-1 Manchester City
Impossible to make this point without sounding like a miserable old man, but, the length of time between full time and extra time gets longer and longer.
Must be nearly 10 minutes now. Have the players recovered? Teams can use FOUR subs now in the FA Cup.

Arsenal knew if they wanted to do anything they had to increase their possession levels. It was far too easy for Manchester City defence.
Arsenal decided to have a go and yes, conceded a sloppy goal, but they looked much better, happier, more creative.
You can't underestimate how well that back three of Arsenal have played today.
Arsenal 1-1 Manchester City
Manchester City have the Manchester derby on Thursday of course, this extra period won't help. Kevin de Bruyne is having a very thorough massage, as City have about 25 medical staff on the pitch.
Arsenal 1-1 Manchester City
Arsenal have been victorious in their last six FA Cup matches that have gone to extra-time, needing penalties to win three of those.

We go again. For another half hour at least.

Yaya Toure has been unbelievable for Manchester City. He has got the ball and been driving forward like he used to.
Arsenal 1-1 Manchester City
Yaya Toure is showing his pedigree in the last half an hour or so, another belting run through the middle and a pinpoint pass into the stride of Leroy Sane, into the area but shut out by the impressive Gabriel.
Arsenal 1-1 Manchester City
Some tired legs, tired minds out there. Gael Clichy puts in a cross which is headed clear before Kevin de Bruyne is booked for a chop on halfway.

Welbeck has got to find a way of getting that ball across to Aaron Ramsey.
Arsenal 1-1 Manchester City
Great effort! Danny Welbeck does brilliantly to beat Nicolas Otamendi on the right of the area, he has Aaron Ramsey in the middle but goes for goal from an improbable angle. What a shot it is too, whipped up and over Claudio Bravo and looking for all the tea in China like hitting the top corner, but it fades away at the last possible second!
He should have squared it - but what a strike!
Arsenal 1-1 Manchester City
Into the last five then. A late winner or extra time?
