Chelsea against United, title decider tonight?

The biggest game of the season so far? Thats what most football pundits are branding this match tonight in Stamford Bridge as. With a United win, could the title chase be coming to an end? It will be interesting to see what way Sir Alex Ferguson will approach this match tonight. Will he try and adopt the 4-5-1 formation that has worked so well for him and United this season in the Champions League campaign? Or will he take an all out attack approach to it and go 4-4-2 with Rooney and Berbatov up front? It will be interesting to see how it will unfold.
