Tension was mounting ahead of the FA Cup match in which Chelsea captain John Terry and Queens Park Rangers defender Anton Ferdinand came face to face for the first time since their infamous clash in October. Both sides urged their fans to behave in a bid to avert any untoward incident.

But again, Saturday night's fixture at Loftus Road was not without its own share of controversies. Terry was constantly booed by QPR fans all through the game. And the clash ended up just as a mediocre affair with the marginally better side eventually winning.

The Blues managed to scrape through on Juan Mata's penalty goal on 62 minutes which, again, looked a highly dubious one. Daniel Sturridge went down in the QPR penalty area. Referee Mike Dean deemed Clint Hill's push responsible for the fall and granted the penalty, much to the disbelief of QPR fans who, in turn, targeted Sturridge shouting "Cheat! Cheat! Cheat!" in a chorus.

The Blues advanced into the fifth round thanks to the win.
