Chelsea midfielder N'Golo Kante is confident Kai Havertz will prove his class.
Kante has been impressed with the young German since his move from Bayer Leverkusen last summer, even if the 21-year-old has seen game time limited of late.
"He has a good talent – good with the ball, calm and he has the ability to make a good last decision in the opponent's half or box," Kante told the club's website. "He's a reliable player for us because we can fund him and use his speed and his technique.
"Obviously he's young and he was a bit injured recently but he always stays positive and keeps a good work ethic.
"It's good to have him in the squad and I'm sure that he will do well in the future."
