Guus Hiddink is hopeful that Gary Cahill will be fit for Chelsea's Super Sunday clash with Crystal Palace.
Cahill is a minor doubt for the London derby with an ankle problem, but Hiddink is confident the centre-half will be cleared to face the fifth-place Eagles.
Chelsea themselves are 14th, 11 points behind Alan Pardew's side.
"Gary Cahill didn't train on Wednesday, which means he has a little problem," Hiddink said.
"He has an ankle injury - some ligaments are a bit tight - but we have several days to go, so I'm not negative about him."
Striker Loic Remy is a doubt for the clash because of a calf problem, but there is no concern over Oscar, Willian and Eden Hazard who sustained minor knocks in the goalless draw with Manchester United.
"We had two tough games against Watford and Man Utd. The physical intensity was high in both games, but we didn't have big damage," Hiddink said.

"Oscar was a bit hurt after a challenge. Willian got some tackles, so did Eden. There was intensity in these games, but they have been recovering so they are okay."
Radamel Falcao has been ruled out until mid-January at the earliest because of a thigh problem, but his fellow striker Diego Costa returns from suspension at Selhurst Park.
