Gary Neville is tipping Kai Havertz for a huge future.
The German midfielder will be playing his second season for the Blues after his arrival from Bayer Leverkusen last summer in a £71million deal.
He scored nine goals and assisted nine goals in his debut season for the Blues.
He also was instrumental in helping the Blues finish fourth in the Premier League and secure the Champions League trophy.
He scored the winning goal for Chelsea in the final against Man City.
Man United legend Gary Neville believes the 21-year old is the talent to watch out for in the Premier League this season.
Neville said: “I actually think Havertz has gone up a level but he is in third gear.
“He could go to fourth gear and to fifth gear. He could become an absolutely great player.
“When he really fills out, and he will do, he is already a great runner with the ball, but he will get more confidence, more belief and in a couple of years he could be someone who is absolutely there.”
