Former Arsenal and Everton defender Martin Keown says David Moyes is capable of upsetting the Gunners tonight.
Keown wrote in the Daily Mail: "Everton must win at Arsenal on Tuesday if they want to finish in the top four. It won't be easy but the good news is that they will have a plan.
"In David Moyes they have a fantastic manager who is a real student of the game. He is tactically very astute: assessing the opposition, pinpointing a weakness and then attacking it.
"He more or less denied Manchester United the title last season by playing Marouane Fellaini in an advanced role and his side exposed Spurs recently by playing direct balls which upset their defensive high line.
"He will have a plan for the Emirates because Everton have a plan in every game they play."
