Fulham appeared to have done enough to force the quarter-final tie into extra-time when American striker Brian McBride cancelled out Damien Duff's 55th minute opener for the Premiership leaders.

But they suffered a killer blow with just two minutes of regulation time left when England midfielder Lampard's shot beat Edwin van der Sar from the edge of the area with a shot that -- just like Duff's earlier strike -- was helped into the net by a deflection off defender Ian Pearce.

Chelsea, still in the hunt for four trophies in Jose Mourinho's first season in charge, were joined in the last four by Championship side Watford, who disposed of managerless Premiership side Portsmouth 3-0 at Vicarage Road.
