Chelsea get the game underway.
The Blues are 11/8 favourites to continue their unbeaten Premier League run with a victory against a United side who have struggled in recent seasons at Stamford Bridge. Sir Alex Ferguson's men have not won in west London in their last 12 attempts in the league and are 15/8 to change that statistic by earning three points today, with the draw available at 12/5. Both sides have lined up with one focal point in their respective attacks and Sky Bet go 10/1 that key strikers Fernando Torres and Robin van Persie both score this afternoon.
Bobby Salim writes: "In 2008, Alex Ferguson had to make a choice between selling either Gerard Pique or Johnny Evans. He sold Pique. I bet Fergie regrets that decision coming into this game, with our attacking power. If Fergie opts to go for a makeshift defence either Mata, Hazard or Oscar will definitely find a way past them. Test of character today with Lamps and Terry gone but a step we must take as a club because supporters now have to get used to the idea of our two living legends not being in the team. 2-1 to the Blues in my opinion."
George Bennett predicts: "An away win for United with them taking an early lead with Van Persie & Rooney my predicted scorers, I think they'll sit back & Chelsea will take advantage pulling back a goal or two but United will grab the three points."
