Frank Lampard took off Reece James, Billy Gilmour and Mason Mount, at halftime against Leicester City.
The Blues struggled in the first half against Leicester City and Lampard opted to take off the three players at halftime.
Lampard insists he doesn’t worry for the young trio subbed off at half-time.
Lampard told BBC Sport: “It is a learning experience. I could have taken more off, or other players off. I am not pulling those out on their own.
“They will be top players for this club and have top careers. But if I have to do something in games I will do it. It was one of those games where I had to do something.
“They will take it on the chin. “We were gifting Leicester space and ease to win the ball back. We are fortunate they didn’t take those chances.”
