The Blues broke the bank and beat fierce competition around Europe to land the talented German, but he has struggled to prove his worth.
Kai Havertz has been backed to regain form and “convince all his critics” at Chelsea by former Bayer Leverkusen teammate Jonathan Tah.
Havertz is struggling to deliver under the weight of his hefty €85 million price tag ever since his summer switch.
The change in environment has been difficult to deal with for the 21-year-old, evident from the fact that he averaged 0.6 G+A in his final season in Bundesliga but is averaging a meager 0.2 G+A in his debut season in the Premier League.
Many have been quick to write off the highly-rated midfielder, who last found the back of the net in the 3-3 draw against Southampton way back in October.
Tah has now jumped in defense of his former teammate as he expects Havertz to come good at Chelsea.
“I’ve been watching the Chelsea games regularly since then [Havertz’s transfer],” the Leverkusen defender told Sport 1.
“It’s super interesting because Timo Werner and Antonio Rudiger also play there. I know what qualities Kai has.
“The game there is different than in Germany. There is a lot of talk in such phases: He has to do this and that because he has cost so and so much.
“But that’s nonsense. Give the boy time; then he will show his enormous qualities at Chelsea too. Kai will convince all the critics over there.”
