Chelsea duo Timo Werner and Kai Havertz need strong personalities to succeed at Stamford Bridge, according to Kevin Kuranyi.

Germany stars Werner and Havertz both joined Chelsea at the start of the season, from RB Leipzig and Bayer Leverkusen respectively, amid high expectations but it has been a challenging start to life for the pair in the Premier League.

After scoring 28 goals in the Bundesliga and 34 across all competitions last season, Werner has found the back of the net on 11 occasions and supplied nine assists for Chelsea this term, including six Premier League goals.

Havertz – who became Chelsea's most expensive outfield player ahead of the 2020-21 campaign – has shown glimpses of his quality with six goals and six assists, though he has largely struggled.

Former Germany striker Kuranyi backed the pair to rediscover their best form in London.

"Of course they were playing a really high level in Germany," 52-time Germany international Kuranyi, who played for Stuttgart and Schalke in the Bundesliga, told Stats Perform News.

"But if you play in a club like Chelsea… I was talking with some friends who play at Chelsea before and there it is very important to have a strong personality to play there.

"They are young players, like Havertz – he is in the first step of his career. He made a big, big step so he needs time to keep his quality at Chelsea.

"I think the first year is very important to learn a lot, to try to do the best, but in the second and third year will be much better."

Thomas Tuchel's Chelsea – fourth in the Premier League – are preparing to face Real Madrid in the opening leg of their Champions League semi-final showdown on Tuesday.
