Jose Bosingwa insists all of Chelsea's squad are fully behind gaffer Luiz Felipe Scolari.

Scolari has returned to his 4-2-3-1 formation in training this week and is likely to start with one striker. Didier Drogba will probably get the nod ahead of Nicolas Anelka while Michael Ballack and Deco are also set to return to the team.

Bosingwa said he has already seen a change in attitude this week.

He said: "All the players are with Scolari. He's our coach and is more than qualified to lead us to success.

"This week I have noticed a greater intensity in training at Chelsea.

"I have seen more energy in all my colleagues because we have a big match against United on Sunday which is vital for the title and we want to win it."
