Former Arsenal midfielder Emmanuel Petit believes there are two areas the Gunners will fall down against Chelsea.
He believes poor execution of set pieces, and winning the ball back will be their downfall.
He told The Mirror: "If they lose the ball, they are not well equipped to win it back. I believe that is where Chelsea have an advantage.
"They 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.
“But they do not seem to score many from set-pieces while Chelsea are always a threat from that kind of situation."
