Chelsea 1 QPR 0

JUAN MATA was spot on as Chelsea marched into the fifth round of the FA Cup. With all the pre-match build-up focusing on Anton Ferdinand possibly snubbing Blues skipper John Terry, the traditional pre-match handshake was scrapped. And the London derby never really got going until Daniel Sturridge took a tumble in the box, with Mata netting the resulting penalty in the 62nd minute. As expected, Terry was jeered every time he touched the ball and was also the subject of numerous abusive taunts. Chelsea fans refrained from using the notorious "Anton Ferdinand, you know what you are" chant, although they did sing "Anton, what's the score?" after the visitors took the lead. Both sets of supporters cranked up the decibel level before kick-off but had little to cheer in a disappointing first half that saw only one shot on target. That came after Mata, playing more centrally in the absence of the injured Frank Lampard, pounced on a Luke Young slip in the 12th minute and unleashed a 15-yard drive too close to Paddy Kenny. Otherwise, the final ball from both sides was sadly lacking, resulting in a succession of speculative efforts that were well off target. A fixture that had seen Chelsea reduced to nine men in October was also a more controlled affair and it was almost half an hour before Mike Dean brandished the first yellow card for a Shaun Wright-Phillips foul on Raul Meireles. Ramires should have done better with great cutback opportunity after being released by a wonderful Mata backheel but neither side deserved to be ahead at half-time. QPR threw on Federico Macheda for Heidar Helguson at the restart as Mark Hughes freshened up his attack. But it was Chelsea who flew out of the blocks, with Fitz Hall booked for handball before Sturridge lashed over after great work from Fernando Torres. The game finally exploded into life on the hour mark. Petr Cech parried a Wright-Phillips cross just too far in front of the outstretched foot of Jamie Mackie and Chelsea surged down the other end to win a penalty. QPR were furious at the award but Mata shrugged off the jeers to score, the midfielder celebrating with most of his team-mates in front of the visiting fans. Ashley Cole was then carded for fouling Wright-Phillips before Chelsea lost Ramires to a serious-looking knee injury. The midfielder appeared to twist his ankle blocking a shot and � after several minutes of treatment � was carried off on a stretcher to be replaced by Oriol Romeu. By that point QPR had already thrown on Rob Hulse, who was denied a penalty in the dying minutes. And there was a flashpoint deep into stoppage-time when Romeu was booked for diving in on Hulse, with Young almost snatching a draw when his 20-yard drive was parried by Cech.
