José Mourinho applauded Didier Drogba after the Blues striker scored his first goal since returning to the club in their Champions League tie against Maribor.
Loïc Rémy gave Chelsea the lead in the 13th minute with his first Champions League goal of the campaign but got injured while he struck the ball and was rapidly replaced by Drogba.
The Ivorian netted a penalty in the 23rd-minute making it 2-0, before the Blues Captain John Terry tapped in as assist from Cesc Fabregas.
Mitja Viler’s own goal made it 4-0 in the 54th minute while Eden Hazard converted Chelsea’s second penalty of the night.
The 23-year-old Belgian then added a sublime finish making it the sixth of the night with the win becoming Chelsea’s biggest-ever Champions League victory at Stamford Bridge.
“I was not expecting him to play 75 minutes,” Mourinho said about Drogba. “I spoke with him yesterday about 30. But the circumstances were that he had to come on.
“We could manage the intensity and his range of movement. In the end it was very important for the team, it was very good for him.
“Strikers like to score goals. He was not for a long time on the pitch in previous matches. His last goal for Chelsea was the most important goal in the history of this club, so to score again at Stamford Bridge is nice for him.
“Didier brings us lots of things. Part of that is being still a good player.”
When asked about how his team have improved from last season, Mourinho said: “We are playing well, we are confident, we are solid.
“We found a good balance. We have now the players adapted to play the game that we were preparing last year, the style that we couldn't manage to do in a perfect way.
“And as I said, good results and confidence brings people to their best. Today is a good example of that – 3-0 at half-time, but they kept enjoying the game and playing and trying to score. We are in a good moment.”
