Chelsea boss Jose Mourinho felt they produced a "perfect" performance with their 5-0 win at Swansea City.

Oscar and Diego Costa both scored twice in the first half to put Chelsea in cruise control before substitute Andre Schurrle grabbed a fifth goal 11 minutes from time to ensure Swansea suffered their heaviest home defeat for 24 years.

"It was a perfect game, everything went in our direction," Chelsea manager Mourinho said.

"To score a goal in the first minute makes an immediate difference. To be 4-0 up at half-time is not game over, especially in the Premier League, but it's a good situation to control and we did that in the second half.

"I was on the bench saying they were similar goals in terms of principles as the one we scored against Burnley in the first game of the season.

"The team is playing with high quality and has a clear identity of playing. Sometimes teams are good and play well without the clear identity, but all this season we are going in a certain direction and have a certain kind of way to play football."
