Chelsea manager, Maurizio Sarri has said he was disappointed with his side’s 4-3 win over Slavia Prague in the Europa League quarter-finals on Thursday night.
Chelsea made it to the semi-finals after a frenetic victory at Stamford Bridge.
However, the Italian 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 added, “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.”
