Arsene Wenger has praised his mature Arsenal players after they gave their all to defeat Olympiakos 2-0 at Emirates Stadium on Tuesday night.

Late second-half goals to Robin van Perise and Andrei Arshavin gave the Gunners another three points in the Champions League and Wenger gave credit to his team who he believes has matured.

"We knew we had to dig deep, not make a mistake and hoped they died more than us and take advantage in the last 20 minutes and that is what happened," he said.

"Overall, I think we dominated that team from the first to the last minute. I was never worried - I always felt we could score.

"I felt we kept composure, we kept going and mentally we were good. We didn't do anything crazy. We have matured and this game shows that."
