Lampard celebrates with Florent Malouda after scoring Chelsea's second goal from the penalty spot.
Back in the team following the death of his 58-year-old mother Pat last week, Lampard wept after scoring the decisive penalty that put Chelsea 2-1 ahead in the 98th minute and got a standing ovation when he was substituted near the end.
He had a decisive impact on the match, too, beginning the move that led to Chelsea's opening goal after 33 minutes and which Drogba completed after Liverpool 'keeper Pepe Reina did well to parry a fiercely struck shot from Salomon Kalou.
