Emi Martinez starts for Aston Villa tonight after returning from injury.
Villa’s penalty shootout hero in the quarter-final against Lille missed their Premier League fixture at Brighton last weekend due to a hamstring injury he picked up against Chelsea last month.
He also missed the first-leg defeat against Olympiakos last week because of suspension, but is fit to start this evening.
Matty Cash also starts in place of the injured Morgan Rogers.
