Lampard, who went on to score himself, claimed not to have seen the controversial second goal as he took the corner, but believes Chelsea deserved the victory regardless of whether it should have been awarded.
"I didn't see it," the midfielder said. "Fair enough if we got lucky there, we got lucky. The referee's given it.
"We didn't have a conversation about it. We scored a lot of goals and created a lot of chances today and over the course of the game we deserved to win.
"It was an amazing game. I thought we played brilliantly. The first half was tough.
"Didier scored an absolute belter. I think we deserved to win that game with the amount we created. Tottenham are a top side but today we won it well."
