Blues seeking first London derby win

The Hoops travel the short distance to Stamford Bridge one point above the drop zone and with a poor away record, while the hosts are still buzzing from European success on Tuesday.Chelsea are facing a defensive crisis ahead of the west London derby with QPR on Sunday. David Luiz and Gary Cahill are both sidelined with hamstring injuries while Branislav Ivanovic misses the final game of his three-match ban after being charged with violent conduct after an incident with Wigan\'s Shaun Maloney earlier this month.These problems leave Roberto Di Matteo with just one recognised centre-back in John Terry and therefore Jose Bosingwa is likely to fill in while Paulo Ferreira should replace his fellow countryman at right-back.Aside from the back four, the manager\'s other issue is whether to rest up his squad after their successful efforts against Barcelona on Tuesday, and with FA Cup and Champions League finals on the horizon, or whether to keep full focus on trying to finish in the top four.As for the visitors, Mark Hughes will make late decisions on both Djibril Cisse and Clint Hill, who are likely to recover from knocks, while it is less probable that Samba Diakite will make the starting line-up. Adel Taarabt is also unavailable for QPR after the midfielder saw red against Tottenham in their last game.
