Chelsea manager Frank Lampard has explained the decision to leave Mason Mount out of the starting lineup in their 2-1 loss to Manchester City on Saturday night.
The Blues lost their first match since October, with De Bruyne and Mahrez's goals either side of a N'Golo Kante strike bringing an end to their six-match winning streak.
The Frenchman's return from injury meant there was going to be some changes, and Mount was forced out as Lampard lined up with a three-man midfield comprising of Jorginho, Kovacic and Kante.
Speaking after the match, the former Chelsea midfielder indicated the quality of the players he has means some will have to come off the bench, and that it did not mean he (Mount) was not good.
"I have a lot of quality in midfield, and Mount is amongst them, but I can't play them all," the Chelsea boss said.
"He has played for us brilliantly from the start. He should be so happy where he is - I'm definitely happy with him.
"But sometimes the decisions have to be made - on the opponent, on the amount of games that we have. Unfortunately, Mason missed out today, but he will be a great player for this club, I hope and I know."
Mount has been one of the club's shining stars this season, starting all Premier League matches prior to the City match, and playing 90 minutes in all but two of them.
Jorginho, Kante and Kovacic were impressive against City, and Lampard will have a tough decision to make going forward on the best formation to accommodate most of his attacking talents.
