He said: "I can only say that Theo is beautiful playing football. To me he is like a machine, it's unbelievable.
"I enjoy it a lot when I see Theo playing in training, and also because he is a very nice guy.
"He is by far the most exciting young English player I have ever seen. His skills are incredible and I am sure that over 100 metres he would get a good time. With the ball also he is very good technically.
"He has a lot of discipline, he is a very complete player. Theo is growing up and I think it's going to be great for England."
