Manchester United moved a point clear of Chelsea following a 4-0 win over near neighbours Bolton at the Reebok Stadium.
Prior to United's visit, the Wanderer’s had kept four successive clean sheets in league clashes at home, in the process taking 10 of a possible 12 points.
United started slowly but gradually gained the ascendancy and were good value for their four goals even if they did need some good fortune to open their account.
Jlloyd Samuel inadvertently handed United the initiative when he turned a Ryan Giggs cross into his own net to give the visitors a half-time lead.
Dimitar Berbatov then scored a second-half brace and substitute Darren Gibson added a late fourth.
Berbatov doubled the advantage turning in the rebound from a Darren Fletcher shot before flicking in Nani's cross.
Nani then set up Gibson to seal the win.
