Diego Costa Is Clever- Arsene Wenger

Arsenal manager Arsene Wenger labelled Diego Costa clever after the striker was involved in the incident which saw Per Mertesacker sent off during Arsenal's 1-0 defeat to Chelsea.

Mertesacker was shown a straight red by referee Mark Clattenburg after just 18 minutes at the Emirates for bringing down Costa when he was in on goal. The forward gave the visitors the lead five minutes later with a strike that eventually handed the visitors all three points, leaving Arsenal boss Wenger frustrated. Wenger had this to say after the match “We had a mountain to climb with 10 men but even then, I believe there was enough there to come away with a 1-1 draw. We cannot influence the decision of the referee. Costa got two player sent off in two games on our side so he's clever. Mertesacker made the challenge but I said he got Mertesacker sent off. You cannot say it's not true. In the first game he got Gabriel sent off and today he got Mertesacker sent off. Did he touch him or not? I will have to watch it again but the fact is the fact. I do not accuse him of anything it's just what happened”

Despite this defeat Wenger was pleased with his team's efforts saying “It's such a shame to put so much energy into a game and come away with nothing. Overall I felt we gave absolutely everything until the end and we should come out of the game with at least a 1-1, even though we were down to 10 men. We had many opportunities, maybe not clear cut but you think one of them we should take. That's our regret that the team put so much effort in and you come out without any points”.
