Lampard added. "Every team has players who can hurt you on the counter attack and Zaha is one of the best but could we hurt him the other way? make him run back more than he ran forward?"
In between, the lively Pulisic also saw an effort well smothered by Guaita after a classy run while Reece James, who was preferred at right-back to the dropped Cesar Azpilicueta, sent in several risky crosses.
"The goals are coming and we're doing well at the back, stopping goals, so it's going well". "We all believe in our style of play and we're enjoying it, so I think it's not a surprise".
"Age is just a number, as you well know, Gary".
A Chelsea victory never looked in serious doubt, although James Tomkins headed wide from a set-piece with Palace's only clear opportunity when they briefly threatened after Abraham's strike.
The early kickoff on Saturday in the Premier League might just be the best game of the weekend in England, as two of the most entertaining teams in the country so far face-off in what should be a fantastic London Derby.
Chelsea had four academy graduates starting and it was one of those - Tammy Abraham - who vitally broke the deadlock in the 52nd minute.
Mateo Kovacic's dribble and pass in an all-star performance found Willian, whose deft touch left Abraham one-on-one to beat Vicente Guaita.
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's impressive form has mirrored Chelsea's, but the 21-year-old said he could not take his performances for granted. Pulisic ensured Chelsea's sixth consecutive league win in the 79th with a header when Michy Batshuayi's shot was deflected and looped into the air.
Chelsea manager Frank Lampard handed midfielder N'Golo Kanté his first league start since October 6 in place of Jorginho, who was suspended.
