After a shock defeat against Stoke, a match against Stoke's former managed would probably be the worst fixture Chelsea fans could have asked for.
Against both Sunderland and Stoke, Chelsea conceded many goals from crosses and set-pieces and I would not bet against that happening again today.
However, in order for them to make the most out of their attacking opportunities, they will need to have the ball for a decent period of time. The table above shows us Palace are not capable of doing so. They by far are the worst at keeping possession.
Of course a long ball side ball side is highly unlikely to have much possession, but Palace's possession rate is scuppered by the lack of ball retention skills. Even at that, a long ball side only needs a moment to create an opportunity and as expressed, Chelsea are not the most organised right now.
Furthermore, a large reason for why they do not keep the ball well is because they do not push many men forward. The archetypal long ball side realises their deficiencies in attack and keeps it tight at the back.
However, because of Crystal Palace's lack of a goal threat, Chelsea will be able to send more players forward to affect the way the game goes. I would not be surprised if someone irregular scored for Chelsea. Furthermore, no matter how tight Stamford Bridge is, it is Chelsea's home ground and the have enough technical players on the field to make it seem bigger than what it actually is.
