Didier Drogba says Chelsea's players thrived in the tense atmosphere leading up to victory over Valencia.

Drogba believes the pressure of needing to secure qualification in the final group game worked in Chelsea's favour.

"There was a lot of pressure but there's four teams so you have to play until the last day," the 33-year-old striker said.

"We had the chance to finish top and our attitude was positive. I think the pressure can sometimes be positive.

"I'm improving since the last few games. I've managed to have more time on the pitch and it's helping me a lot."
