Chelsea boss Carlo Ancelotti believes the key to beating Arsenal today will be silencing Cesc Fabregas.
Ancelotti is banking on fit-again Frank Lampard to lockdown his Spanish rival.
He said: "They are both fantastic midfielders. Fabregas scored a lot of goals, as Lampard does, and they can be men of the match. I hope it is Lampard!
"We know it is very important to control midfield if we want to win and stop Arsenal."
