Frank Lampard pleaded for time for his Chelsea rising stars to become ‘killers’ in the Premier League.
The Blues boss’s £140million pair, Timo Werner and Kai Havertz, finally found the target again as Morecambe were put out to the sword.
Werner ended a 12-game goal drought while Kai Havertz grabbed his first in 15 games.
But Lampard said: “People talk about the youth in the squad but what we can’t ask for the youth is to be killers and to be consistent.
“That will come but for the moment their contributions are good.
“I’m pleased for Timo because strikers want to score goals.
“He has had plenty of near misses and in this game it wasn’t easy as they didn’t leave a lot of space in behind.
“But we understand at the club that some of the greatest players who have come into this league haven’t found it easy at the beginning.”
England midfielder Mason Mount put a strong Blues side ahead on his 22nd birthday from 25 yards.
Werner and Callum Hudson-Odoi struck either side of half time before Kai Havertz headed the fourth with five minutes left.
Lampard, who confirmed he is expecting his child, added: “When you look at the top of the scoring charts you find players who are 28, 29, who have had to work their way to the top and they produce.
“With our players people look at price tags and expect them to reach those kinds of levels. But there is work to be done to get to a point where we can bridge that gap.”
Asked whether he feared more sleepless nights with his impending new arrival, Lampard added: “Chelsea doesn’t keep me up at night thankfully. I’m just very happy.”
Morecambe boss Derek Adams said: “When I looked at the teams to start with, the team that Chelsea put out I wasn’t too happy.
“But he showed a great deal of credit to the FA Cup.”
