Chelsea ace Kai Havertz has been impressed by Billy Gilmour this season.
Gilmour this week made his first start of the season against Krasnodar after knee surgery in the summer.
"We all know that Billy is a very talented player with a lot of qualities," he said.
"He is still very young like me but in the Champions League he played very good and we are all very happy with him.
"He has a big future ahead of him."
