Aston Villa boss Unai Emery says he has full confidence in Robin Olsen.

The Swede will be between the posts tonight in the first-leg of the Europa Conference League semifinal against Olympiakos. Emi Martinez will miss the game due to injury.

Emery said: "Robin Olsen has done really well every day in training, and when he has played, he has helped the team, so everyone believes in him and trusts his performances.

"On Saturday he played 45 minutes against Chelsea, where he saved us.

"He is a humble man who hopefully can help us."
