Manchester United and Arsenal will both be looking to book their places in this year's Europa League final.
United's place in the decider is all but confirmed as they take a sizeable 6-2 aggregate lead into tonight's semi-final against Roma.
Ole Gunnar Solskjaer is expected to name a strong side, despite the fact they have a run of four games in 8 days coming up.
Arsenal have a much bigger battle on their hands.
They are 2-1 down to Villarreal ahead of their match at The Emirates Stadium in North London.
Both games kick off at 8pm.
