Battle of Bridge - Chelsea v United

United travel to Chelsea as underdogs .Chelsea go into the clash in arguably their finest form of the season. They haven't conceded a goal in Bridge since the opening day of the season and for the first time they are scoring goals freely.

The United back four is shaky and there is too much defensive errors .Even with the first-choice pairing of Ferdinand and Vidic the champions have still only kept one clean-sheet in their past four league games, while the team's recent record against fellow top four sides will also give fans cause for concern.

The place where United really struggle now against the other teams of big four is midfield . They are devoid of a play maker in the central of the park . Arsenal almost made them pay for it and two weeks back Mascherano and Lucas ran riots through the midfield .

United will hope to welcome back Vidic (calf), Ryan Giggs (knee) and Dimitar Berbatov for the trip but Ferdinand (calf) has been ruled out .Gary Neville sits out the match through suspension.

Chelsea duo Yury Zhirkov and John Mikel Obi are both available after recovering from injuries.The Blues' only absentee is right-back Jose Bosingwa, who may require surgery to treat his knee problem.
