Former Chelsea fullback Glen Johnson says they have the edge on Manchester United today.
Johnson believes his old side have the advantage going into today's game.
“The result of this game all depends on which Manchester United team turns up, one week they're one of the best teams and the next week the worst - this will also be down to Chelsea's performance to keep a few of United's top players quiet," Johnson told CheltenhamGuides.com.
“I fancy Chelsea. They're in fine form and look solid. They're more consistent than United. I think United have more power going forward when they're on-song but they're on-song one in three games. I think 2-1 Chelsea."
