Former Germany striker Klaus Fischer has backed Kai Havertz to prove himself at Chelsea.
The 22-year-old sealed a £70m move to Chelsea from the Bundesliga side Bayer Leverkusen but struggled to adapt to the Premier League immediately.
Havertz eventually came through for Chelsea in the Champions League final, and Fischer believes that the young player will eventually shine through at Chelsea, and backed his goal in the Champions League final to be first among many.
Fischer told Goal: “When you come to a different country and to a different team as a young player, you have to establish yourself.
“I think that he prevailed, seeing as he scored the deciding goal in the final in the Champions League and also because he has a German coach who teaches him the German virtues.
“He needs to demonstrate these virtues in England too, because they probably play the best football in terms of speed and physicality.
“I do believe that he has what it takes to assert himself because he can score goals.
“He’s also a smart player who knows how to play, but a young player who is not the finished article yet in his development. That goal has probably given him an incredible boost and he will continue to score goals in England.”
