Manchester United manager Jose Mourinho admits that Chelsea are the better team this season, and have an advantage in Sunday’s clash.
The Blues face their former manager at Old Trafford with a big lead in the Premier League standings, and Mourinho has already started explaining why his side are up against it.
"The best team at the end of the season is the one who is champions and we are far from it" he said. "This season Chelsea are a much better team than us.
"I know you like to criticise me. When I was winning titles with Chelsea you were criticising the style of play. At the moment you don't do it.
"Now, to be the best counter-attacking team in the country is not to be criticised; it is an amazing thing."
Mourinho also insisted that the Blues have also benefitted from missing out on European football, saying that fatigue is more of an issue for the Red Devils.
"We don’t train. We recover from matches," he added. "We try to give the players the best conditions to recover but, honestly, on the pitch there are no conditions to work.
"It's a bit difficult, especially for some players.I think for some of the boys it is not a big problem to play match after match with two days' difference. For some others it is more difficult – their nature, their ages, their DNA. It is not so easy.
"We have important injuries and we do not have so many players to rotate. In some positions, we have no choice. Of course, [Chelsea] are much better prepared for the game than us."
