Jose Mourinho will be quaking in his boots at the arrival of Manchester United this Sunday. Or at least that used to be the case when United were a table-topping force in the Premier League.

Under the stewardship of David Moyes, United have failed to show their full potential yet this year, with their somewhat inconsistent form leaving them seventh in the Premier League ahead of their clash at Stamford Bridge. Chelsea on the other hand are two points of the top, despite their lack of options up front with Fernando Torres and Samuel Eto’o both misfiring this season.

Having watched their side struggle to find top four form this year, our friends over at Full Time Devils have put a top notch preview together for your viewing pleasure and explain just why United can’t afford to lose to Chelsea on Sunday.
