Bayer Leverkusen manager Peter Bosz says that Kai Havertz is an "intelligent boy" that can handle pressure in the wake of ongoing links to Chelsea.
The midfielder has been earmarked as a Chelsea target and has been widely tipped to leave Leverkusen this summer as the Blues prepare a €76 million (£70m/$87m) offer for the midfield star.
Chelsea have already signed Hakim Ziyech and Havertz's international team-mate Timo Werner this summer, and the addition of the 21-year-old would only add to what has been a big-spending window at Stamford Bridge following last summer's transfer ban.
