Frank Lampard has no doubts about his young Chelsea players despite a poor performance in Sunday's 1-0 win over Leicester City.
Billy Gilmour, Reece James and Mason Mount were all dragged at the interval following a sub-par first-half at the King Power.
"I could have made different changes as well," Lampard said. "Mason has played two games in a week and gave a lot of input against Manchester City for 90 minutes.
"Reece James hasn't played for a long time, since lockdown. Billy was the same. These are contributing factors around it. They are going to be top players for this club no matter what. They are going to have top careers in football. They will have really, really top careers because of the players they are.
"Whether you can call it a learning experience, it was just a factor of how I saw the game. They can take it on board. They are all good lads, all train well and all have a good work ethic. I've never had a problem with the three of them at all. I've got no worries; it was just the circumstances today."
And Lampard added that he could have made more changes at half-time.
"It is a learning experience. I could have taken more off, or other players off," he continued.
"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. All thee subs, in their own way, livened up the performance."
