There was a first Premier League start for 19-year-old right-back Reece James, dropping captain César Azpilicueta to the bench. "It was a really good individual performance from Reece because Zaha is a big threat on the flanks and one-on-one", Lampard said.
"The goals are coming and we're doing well at the back, stopping goals, so it's going well".
"It's that step up - a lot of us want to make that step up and prove we are ready".
"Crystal Palace are a good side, they defend well as a team and they frustrated our style of play".
"I know I trust in Reece defensively, so it was a really, really impressive game from him, and he's going to get much better". He broke the deadlock soon after.
Christian Pulisic thereafter bagged the club's second on the day and the game ended with Willian enjoying his first-ever win as the Blues captain in the Premier League.
He is also the second youngest player to score 10 Premier League goals for Chelsea after Arjen Robben and, having been given the confidence of the Blues' coaching staff, he is proving to be better than numerous big-name and expensive No.9s the club have had in recent years.
Pulisic, whose goal came on a close-range header after he was twice denied earlier by Palace keeper Vicente Guaita, again won praise from Chelsea manager Frank Lampard.
The win was the sixth in a row in the Premier League for the young Blues, who are comfortably in the Premier League's top four.
It is unlikely that Chelsea will be able to compete for the title this season but they have progressed quickly under Lampard with their youngest squad in recent memory.
Pulisic, who has now scored five goals in Chelsea's last three Premier League games, wrapped up the victory with his 79th-minute strike, heading in after substitute Michy Batshuayi's blocked shot bounced up for the United States global.
