Chelsea midfielder Mateo Kovacic says defeat to Manchester United wasn't good enough.

Chelsea's cushion to the chasing pack now stands at just one point follow Monday night's defeat.

"We are still fourth so we are still in a good position but we need to wake up because they are coming from behind," said Kovacic.

"We need to play these next games like we were playing in the beginning of the season and change some things as well, obviously.

"We need to improve a lot because we have tough games ahead of us and we have to be focused.

"We have to train hard every day, to prepare our games better and try to avoid our mistakes because we are making too many mistakes in these kind of matches and you get punished.

"We have a good week ahead of us to prepare for Tottenham and to play a good match. We know this match means a lot for us because Tottenham are close behind us so we need to prepare ourselves quite a lot to win this game at home."

He added: "We are still a very young team and we need to improve a lot. Now we will see if we are a great team because we have some tough matches to fight for the fourth position and we need to show ourselves."
