Manchester United are being helped towards the title by The Premier League, that is the view of Chelsea manager Avram Grant.
The Blues are incensed with a fixture situation that sees them play their rescheduled clash at Everton on April 17, just three days after they play Wigan.
Both games come before Chelsea meet Manchester United in what could be a title decider, and Grant feels The FA have handed the champions a massive advantage with the decision.
"I don't understand why we need to play on Thursday when we play Monday against Wigan and we have also the Champions League," Grant said.
"I think that's unfair, I think when you come to the end of the season you need an equal situation for all the teams. Now they have an advantage over us.
"Of course when we come to the game we will do everything to win but I think it's unfair what is happening and I don't understand why. I think we need to fight it in any way we can."
Chelsea are also determined to let every fan know that the decision was made by The Premier League â€œsolely on television grounds and as a result of the Premier League board failing to resolve schedule issues between broadcasters.â€
