We are now in the final leg of the semi-finals, and both English sides are very much in contention.
Arsenal won their first leg against Valencia 3-1, so have the advantage on aggregate. Valencia need at least a 2-0 win to go through, but Arsenal will have an even big advantage if they can score away from home.
Chelsea meanwhile drew against Eintracht Frankfurt 1-1 in their opening match, but already have the away goal, and are now playing at home. An all-English, and indeed an all-London final, is still on the cards.
Valencia v Arsenal is on BT Sport 2 at 19.15 (kick-off 20.00).
Chelsea v Eintracht Frankfurt is on BT Sport 3 at 19.15 (kick-off 20.00).
