Aston Villa boss Unai Emery admits they fell short of standards in defeat to Olympiakos.

Villa lost the first-leg of their Europa Conference League semifinal 4-2 at home with Ollie Watkins and Moussa Diaby on the scoresheet.

Emery said: "We didn't play like we are playing and we need to keep being consistent.

"They deserved to win and they are a good team. It's not about luck. We didn't play well. We have to play better."

Villa captain John McGinn also admitted: "There were mistakes all round tonight and we'll take responsibility.

"We have a mountain to climb but we know we're capable. The manager was still positive in there.

"There's still a long way to go."
