"Every game in the Premier League is hard, particularly against a team as organised as Palace," said Lampard.
"In the first half we started well, then allowed our tempo to drop, but when we came out in the second half with the intent that we did, we won the game relatively comfortably - a nice, solid win with a clean sheet.
"We've had teams come here and be difficult to break down, it's a test of not only how you unlock the door, but can you switch on to make sure you don't get hit by the sucker punch?
"I was really delighted with the game management in a game like today. I got as much joy out of Kurt Zouma and Fikayo Tomori's performances in defence, and the midfielders shielding in front of them, as I did our attacking play."
