Dimitar Berbatov scored a second-half brace as Manchester United swept aside Bolton to restore their one-point advantage at the Premier League summit. Jlloyd Samuel inadvertently handed United the initiative when he turned a Ryan Giggs cross into his own net. Berbatov stretched the lead, turning in the rebound from a Darren Fletcher shot before flicking in Nani's cross. Fabrice Muamba had earlier gone close for Bolton, but Nani set up substitute Darron Gibson to seal the win late on. A point ahead in the title race at the afternoon's outset, United briefly relinquished the lead to Chelsea, who hammered Aston Villa 7-1 at Stamford Bridge, but re-established their slender advantage with a performance of growing authority. Bolton provided stern opposition in the initial stages, weathering an early United storm and testing Edwin van der Sar's reflexes through Johan Elmander and, notably, Muamba, who drew a flying, fingertip save from the United keeper But Samuel's own goal - the 11th that has gone in United's favour this season - was a hammer blow, and once Berbatov had tucked home to double the champions' lead in the 69th minute, the spirit slowly ebbed from Owen Coyle's side.
