Arsenal legend Martin Keown has suggested that the balance in midfield will prove to be the key for Arsenal if they want to beat Chelsea on Sunday.
The second-placed Gunners host league leaders Chelsea at the Emirates Stadium on Sunday and former defender Keown has identified the area where Arsene Wenger's men can overcome Jose Mourinho's champions-elect.
"Arsene Wenger hasn't gone with two holding midfielders very often, he likes to be creative in that midfield area," he told Sky Sports News HQ.
"That has actually been a little bit of a weakness for Chelsea this season. Cesc Fabregas has played that role for them and Nemanja Matic has done it.
"So it's about getting the right balance in midfield. I think Arsenal will look to take the game to Chelsea and Chelsea will maybe use an extra midfield player in there.
"Jose Mourinho usually finds a tactic to stop the opposition from playing and Wenger tends to just go for it."
The Gunners are currently 10 points behind the Blues and will need to take all three points if they want to maintain their title challenge.
