Wenger dismissed criticism this morning of the German's performance in defeat at Liverpool.
"He was like everyone on Saturday, he wasn't on a good day. He works hard in training to improve, there's no one to ostracise from that game. He has done well but adapting to the Premier League. I don't want to put too much pressure, he is adapting to the pressure of the Premier League.
"He can deal with the criticism."
