One minute added on.

Eden Hazard's free-kick is past everyone and punched away by Kevin Trapp.

TrevorOakley1 Just put the Chelsea game on. Did Chelsea play last night as well because they look absolutely goosed. Seen some awful touches in the five or so minutes I've been watching.

Free-kick to Chelsea as Jonathan de Guzman fouls Eden Hazard.

Pedro almost finds Eden Hazard with a through-ball but it's cut out. Now Ross Barkley has a shot from long range but it's wide.

As far as extra times go, this is decent.

What a chance! That should have been a goal! If he had concentrated and put his foot through it it would have been a goal. They should have punished Chelsea there - it came from Eden Hazard trying to take players on in the wrong areas. Maurizio Sarri was going mad on the side.

David Luiz is the hero!

It's a quick break from Frankfurt. Filip Kostic flies away down the wing and finds Sebastien Haller. The sub's shot isn't good enough but still bounces past Kepa, with Luiz acrobatically clearing off the line.

A proper contact there though and Luiz wouldn't have stood a chance.

Ross Barkley tries to find Eden Hazard, but he's nudged off the ball by a defender. Will Hazard play at Stamford Bridge again after tonight?

Chelsea break from the corner, with Eden Hazard carrying the ball forward, but Gonzalo Higuain's low cross is poor and cut out. Maurizio Sarri has his head in his hands.

That was a big chance.

Terrible play by Chelsea as Davide Zappacosta holds the ball up and then boots it off Pedro for a Frankfurt corner.

You get a fourth sub in extra time these days. And Chelsea use it to bring on Gonzalo Higuain for goalscorer Olivier Giroud.

Chelsea have a corner now as they get their final sub ready.

Eden Hazard takes and Cesar Azpilicueta hooks it over the bar.

For those asking, the away goals rule does count in extra time. So a Frankfurt goal would mean Chelsea need two. And remove the chances of penalties.

Speaking to BT Sport, Arsenal striker Alexandre Lacazette said: "We reacted well to going behind and we knew we had to score a minimum of one goal tonight. Auba was unbelievable tonight with an incredible hat-trick, so thanks to him.

"We have played badly in Premier League during the last month and now we have to use this opportunity. We want to play in the Champions League next season and we want the trophy."

Wonder if Chelsea fans would say sorry for the booing if Ross Barkley scored the winner. He has a go from 25 yards but curls over the bar.

Speaking to BT Sport, Arsenal striker Pierre-Emerick Aubameyang said: "We have learned from last season and this year we didn't make the same mistakes. Now we are through to the final."

On his relationship with Alexandre Lacazette: "We have talked a lot about our relationship and it is a pleasure to play with him, above all when you win games like this. It is a final so it doesn't matter which team we play, we have to give everything and win."

Can Chelsea join Arsenal in the final?
