Manchester United on Sunday defeated Chelsea by two goals to keep the title race open.
Marcus Rashford put the hosts in front in the first half before Ander Herrera made it two after the interval.
Speaking after the game, Manchester United boss Jose Mourinho said to Sky Sports: “Maybe we didn’t ‘rest’ players ahead of Thursday, we just chose the team we thought was the best team.
“We went to Stamford Bridge in the cup with same tactics, the game was totally controlled with 11 players, only the decision that made us play with 10 men for the second half and 10 minutes in the first half, gave Chelsea a chance to be dominant.
“We knew that playing this way would be very difficult for them.
“Marcus Rashford played fantastically well. He had a very good game at Stamford Bridge in the cup, exactly the same chance to score, because he is faster than their defenders.
“Today he scored and it gave the team more confidence, more stability.”
Speaking to Match of the Day, he said: “Chelsea are the best counter attacking team in the country and we controlled them very well. I’m really happy with the boys. I’m happy – not because it’s Chelsea, it’s because we need these three points.
“I don’t feel extra joy at beating Chelsea – we beat the leader. It doesn’t matter if the leader is Chelsea or another – we beat them convincingly. Nobody can doubt our credit to win the game.”
