Frank Lampard was delighted with Chelsea's 7-1 win over Grimsby Town to book their place in the Carabao Cup fourth-round.
Academy graduates Reece James, Marc Guehi and Billy Gilmour all started, while back-up Michy Batshuayi took his chance by scoring a double.
Lampard said: "It was pleasing on a lot of levels. It was not complete.
"But I'm pleased some players who have not been playing so many minutes played, some debuts, and the young lads who came on improved the team which was nice. It's nice to get that first home win.
"I thought Gilmour ran the game from midfield, and Guehi was solid. They've been outstanding this year.
"And the young subs showed how comfortable they are on the ball. Now the hard work starts to get in the team regularly.
"It says a lot about the academy, and nights like this give the opportunity to mix the team up and give them a chance, it gives good recognition to the academy."
