Chelsea can focus on the FA Cup as they are “already Premier League champions”, says Jose Mourinho, manager of quarter-final opponents Manchester United.
Antonio Conte’s side, who will host cup holders United in the last eight in March, hold an eight-point lead in the title race with 13 games to play.
Chelsea progressed by beating Wolves 2-0 in the fifth round, while United came from behind to win 2-1 at Blackburn.
“The FA Cup is something important for them,” said ex-Blues boss Mourinho.
Chelsea are odds-on to claim the top-flight title for the second time in three years, after Mourinho’s success with the club in the 2014-15 season.
The Portuguese was sacked seven months later, with the side just one point above the relegation zone.
In his first season at Old Trafford, he has led the club to the last 32 of the Europa League – with a 3-0 lead over French side Saint-Etienne going into Wednesday’s second leg – and an EFL Cup final against Southampton at Wembley on Sunday. United are sixth in the Premier League table, two points outside the top four.
“I have so many things to think about,” said Mourinho.
“I have to play Saint-Etienne and play the (EFL Cup) final and hopefully another opponent in the Europa League. I have to fight for the top four positions in the Premier League.
“Chelsea can only think about that because I think they are champions and have nothing else to play for.
“It is possible to win three, two, one or no trophies. When we are in the competitions, we are going to fight. In the EFL Cup, we have a 50% possibility of winning and we have to fight for it to become a title.”
