Chelsea midfielder Frank Lampard was well aware he and his team-mates had to work hard for their 4-0 win over UEFA Champions League minnows Nordsjaelland.
Juan Mata put the reigning European champions ahead in the 33rd minute but Chelsea did not manage to increase their lead until the 79th minute and Nordsjaelland came close on a couple of occasions to drawing level.
David Luiz's free-kick gave Chelsea some breathing space, though, and then Mata and Ramires added further goals in the last eight minutes to seal the victory.
Lampard, Chelsea's captain for the night in the absence of the rested John Terry, told Sky Sports HD2: "It was a great result for us, it was a tough game.
"They were a bit of an unknown but we know they played good football and we had to bide our time, we put the hard work in and all the goals came at the end."
Asked if he was concerned at any point, Lampard said: "A little bit, because this is Champions League football.
"There are no easy games and at 1-0 they created a few half-chances, hit the post in the second half, but once we got the second goal that was it and we dominated from there on."
