David Luiz looked to be in good shape as he prepared for Chelsea's crunch Premier League clash with Manchester United at Stamford Bridge on Sunday.

The Brazilian defender may feel that he has a point to prove against new Red Devils boss Jose Mourinho after the Portuguese coach sold him to Paris Saint-Germain during his second stint at Stamford Bridge.

Luiz was brought back to Chelsea from PSG in the summer transfer window by new manager Antonio Conte.

And the Brazilian certainly looks like he is ready for action as he worked on his balance ahead of the visit of the Red Devils.

Chelsea head into the game looking to build on their 3-0 win over Leicester City last weekend.

United, meanwhile, are looking to gain momentum after their 4-1 victory over Fenerbahce in the Europa League at Old Trafford on Thursday night.
