Jose Mourinho reignited talk of a campaign against Chelsea, even after taking a huge step towards the Barclays Premier League title on Saturday. Eden Hazard’s first-half goal gave the league leaders a 1-0 win over Manchester United, but there was controversy when United were denied a late penalty. Ander Herrera went over under the challenge of Gary Cahill but referee Mike Dean adjudged the Spaniard to have dived.

Replays showed some contact between the two players during stoppage time but Herrera looked to have moved his leg to provoke a collison. And Mourinho took the opportunity to pick at an old wound in his long-running feud with Sky Sports. ‘I am happy that it was not a Chelsea player,’ he said. ‘If it was a Chelsea player, in this moment on Sky it would be “somebody's crimes, cheating, the champions of the team without fair play” and this kind of things.’ Mourinho was angered earlier this season when Sky used the headline ‘Diego Costa crimes’ in their analysis of Chelsea’s Capital One Cup semi-final win over Liverpool in January.

Costa was later suspended for a stamp on Martin Skrtel and the Chelsea manager saw Sky’s coverage as contribution to the player’s three-game ban. He also hinted in his pre-match press conference that Chelsea were disliked and abused because they were making the Premier League ‘boring’ by leading from start to finish. ‘Because it's a Man United player tomorrow nobody remembers,’ Mourinho added. ‘The conspiracy doesn’t go on, I'm happy it's not a Chelsea player.’
