Chelsea boss Frank Lampard was delighted for Reece James after their 4-4 Champions League thriller with Ajax.
James made history by becoming the youngest Chelsea scorer in the Champions League.
Lampard said, "Reece is a fantastic young player. He gives what you saw, and he will get much better because he's 19.
"I felt we needed to change to get a bit more for us on the right-hand side. Reece can deliver crosses with great quality. He's powerful and joins in. He knows we have Azpi there, our captain, but there are things we can do to change sometimes.
"He's going to be a top player for the club. He's got great quality. When you look at the modern full-back, the requirement to go forward and be a threat, hopefully Reece can do that for us."
