Chelsea manager Thomas Tuchel has warned Kai Havertz 'he cannot rely on endless talent' but says the fellow German has the potential to 'become a huge part of this club'.
Havertz, 21, was a highly-rated £89million acquisition from Bayer Leverkusen in the summer but has struggled to get going at Stamford Bridge so far, scoring only once in 17 Premier League games.
The Germany international failed to regularly feature under previous manager Frank Lampard but played the full 90 minutes under new man Tuchel in his opening game against Wolves.
