Cazorla struck twice in the 2-1 win.
Wenger said: "He fights until the last second of the game and gives absolutely everything. You tell him to play left, yes, central, yes, right, yes.
"He doesn't say, 'I can only play in the middle'. He has a fantastic, humble attitude to help the team and he plays where he's needed, that is fantastic.
"He's so short and with a low centre of gravity - a bit like Jack. So his change of direction is very good. You don't know if he is right-footed or left-footed. I don't really know myself."
