Premier League: Jose Mourinho says his Chelsea team is 'not perfect'

Jose Mourinho : Takes his side to QPR on Saturday

Manager Jose Mourinho says he is content with Chelsea’s current position across all fronts but insists his side can still improve.

The Blues are top of the Premier League and unbeaten in the division, as well as top of their Champions League group and through to the quarter-finals of the Capital One Cup.

Mourinho welcomes QPR to Stamford Bridge for a west London derby on Saturday, boosted by the return of top-scorer Diego Costa.

"In terms of objectives, the pragmatic ones, the numbers, the results, we are where we want to be," Mourinho said.

"First in the Champions League, first in the league, quarter-final of the League Cup.

"In terms of numbers we are there but in terms of performance and the quality of the team – no team is perfect.

"We are not perfect, but I'm happy with what we are doing and where we are.

"It’s not difficult for me to see where we need to improve. This team is giving me more work to bring them to the level of my previous Chelsea team.

“Almost all of that team were end products; top players. End products are one thing and players with great talent are another.

"That's why I came here. I knew exactly what I was going to have when I came here last year."
