Mata settles all-London Cup clash

Juan Mata's hotly-disputed penalty helped Chelsea secure a 1-0 victory in a tempestuous FA Cup fourth-round tie at west London rivals QPR.

A match that for an hour was completely devoid of the kind of flashpoints that marred October's Barclays Premier League meeting suddenly had one when Clint Hill was harshly adjudged to have bundled over Daniel Sturridge.

Mata stepped up to score the only goal of a game dominated by the reunion between Chelsea captain John Terry and Rangers defender Anton Ferdinand, neither of whom put a foot wrong following what had been the most combustible of build-ups.

The match itself was always going to struggle to live up to the drama that preceded it, which culminated in full body searches for fans entering the ground and the cancellation of the traditional pre-match handshake.

The former was prompted after police confirmed on Friday night that they were investigating allegations Ferdinand had received "malicious communication", although they refused to reveal whether it contained a bullet.

Ferdinand and Terry were spared having to shake hands with each other after the Football Association agreed the clubs did not have to undertake the traditional pre-match ritual.
