Former Arsenal and Chelsea midfielder Emmanuel Petit has praised the "great balance" of the Stamford Bridge side's current squad ahead of their Premier League match against Arsenal this afternoon.
Jose Mourinho's men are unbeaten in the league this season, leaving them at the top of the table.
The Frenchman, who retired in 2005, told The Mirror: "I think Chelsea have a great balance to their squad and they have a bigger physical presence. You look in midfield and Chelsea have Cesc Fabregas and Nemanja Matic.
"You look at the central defence, with John Terry and Gary Cahill. Arsenal are great when they can play their normal game, on the grass, passing along the ground.
"Arsenal have players who are great on the ball, don't get me wrong. But when they lose possession, they seem to have a problem. When they can control a game, great. At times, it seems like Arsenal have forgotten how to defend. They are missing some power in their team."
Chelsea secured a 6-0 win in this fixture last season.
