Chelsea left it late to clinch a 3-1 victory over 10-man Norwich that was marred by a serious injury suffered by Didier Drogba on Saturday.
Andre Villas-Boas’s side were in danger of being held to a draw at Stamford Bridge by newly-promoted Norwich when Grant Holt punished a mistake from Blues goalkeeper Hilario to cancel out Jose Bosingwa’s opener.
Drogba was stretchered off soon after when he landed heavily following a collision with Norwich keeper John Ruddy.
But Lampard ensured Chelsea won for the second time in three league games under Villas-Boas when he drove home a spot-kick with eight minutes remaining before Juan Mata marked his debut following his move from Valencia with a goal in the final moments.
