QPR skipper Joey Barton says Chelsea will focus on David Luiz as PSG's weak link.

Barton expects Chelsea to win their Champions League tie with PSG comfortably.

He told Le Parisien: "David Luiz could be the weak point. Nobody knows this better than Jose Mourinho. He will exploit his weaknesses.

"The lack of affinity between Ibra (Zlatan Ibrahimovic) and (Edinson) Cavani also concerns me.

"I love the Uruguayan but he resents, obviously, being in the shadow of Zlatan."
