Jose Bosingwa is convinced the arrival of Guus Hiddink has had a positive affect on everybody at Chelsea Football Club.

The Dutch coach replaced the sacked Luiz Felipe Scolari last month, and suddenly the Blues look capable of challenging Manchester United for the top honours again.

Although the Blues are still four points behind the Reds, they have been given hope in the Premier League race after Liverpool won 4-1 at Old Trafford on Saturday.

And with a place in the FA Cup semi-final already assured and the last eight of the UEFA Champions League on the horizon, Bosingwa has hailed Hiddink’s coming.

"The spirit in the squad has risen and we are playing much better," he said. "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. 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. A club like Chelsea is built to compete at the latter stages of competitions like the UEFA Champions League."
