Arsenal boss Arsene Wenger is handing Alex Song a big chance to stake a first team claim tonight at Slavia Prague.

The Cameroon midfielder will play at centre-half and Wenger said: "It will be a big test for him.

"He is very strong in one against one, reads the game well and is calm, good on the ball, that is important for us.

"If you ask him, he prefers to play central midfield, but I feel that he just wants to play.

"I never had any doubts about him. There are things that you cannot cheat when you see someone everyday in training."
