Jose Mourinho has been discussing his side’s performance against FC Porto in the Champions League and Diego Costa’s contribution to the 2 – 0 win that sealed that place at the top of the group.

Costa missed three glorious chances to score but his first touch, poor strike and Iker Casillas let him down.
Speaking on his star striker’s performance, Mourinho said Diego Costa has been in poor form this season because of a lack of confidence.

He said: “It’s clear but what is also clear is his effort, commitment and great movement, which is something he hasn’t had in the last couple of months. Tonight it was great. 
“The first goal was obviously an own goal but his movement was great when the pass arrived. Last season he would have scored immediately but this season he couldn’t.
He continued: “With the second chance when he faced the keeper on his own, you could immediately feel the lack of confidence because the first thing he did was not attack the goal but look to the linesman.
“When he did that he lost an important second and his last touch on the ball was not the best.
“He could have scored two or three goals today. There is a lack of confidence, clearly, but his attitude was very good and his movement was much better, so goals are coming.
“I took him off not because I was unhappy with his performance but to give something different to the team, to attack the spaces with faster people.”
