Jose Bosingwa has revealed Chelsea's players are buzzing after recent results under new boss Guus Hiddink.

"After recent results the spirit in the squad has risen and we are playing much better," he said on skysports.com.

"The mentality of the squad has changed and that is partially due to the arrival of Hiddink. We now use a different system and have improved as an attacking force.

"The return of Drogba to top form is also crucial for us. I think he is very happy at the moment and that is positive for us. He is one of the best strikers in Europe and his quality is unquestionable.

"Although it was sad, what happened under Scolari, that is all in the past now. Our only interest now is to play well for Hiddink and to do our best in all competitions.

"A club like Chelsea is built to compete at the latter stages of competitions like the Champions League."
