Maurizio Sarri disappointed with Chelsea victory

Sarri’s side qualified for the semi-finals after a frenetic victory at Stamford Bridge, but the Chelsea manager was distressed by his side’s start.

He told BT Sport: "We started very badly in the second half but I'm really really happy because we played well in the first 45 minutes and we are in a European semi-final which is very important to us.

"We knew very well the match was going to be difficult. They ran a lot and with quality - lot of metres at high speed."

Chelsea striker Olivier Giroud said: "We started well with good intentions. We have been efficient up front and solid at the back but we dropped our intensity after the break. This team never gives up and the last 10 minutes was box to box. It was a good fight and now we are in the semi-finals."

Chelsea defender Cesar Azpilicueta said: "It is a mistake we are making very often and we are conceding early goals in the second half of games. We were 4-1 up but they put us in trouble and we were risking it. We were suffering until the end.

"It is not the way we want to win the trophy but we are in the semi final and hopefully we can get through."
