Havertz signed for Chelsea from Bayer Leverkusen last month, and has made five appearances, scored three goals for Frank Lampard’s side.
This 21-years old scored a hat-trick as Chelsea rough to a 6-0 victory against Barnsley in the third round of the Carabao Cup, but is yet to score in his four Premier League appearances. The German international said that the league is “more severe” than what he experienced in the Bundesliga due to the fact that “everybody is at a very high stage”.
“It was difficult for me, especially because the Premier League is different a lot, ” Havertz said to Chelsea’s official website. “It’s more severe and I noticed that in the first few games.
“The severe in the duels and the runs is much higher. It’s a completely different league and the games were very much exhausting.
Bundesliga isn’t worse but I noticed the differences. It seems to me like there aren’t any average or bad players here – everybody is at a very elevated level.”
Havertz was okay with the way he performed against Barnsley, but says he is aware it will take him time to adjust to his new environment and build relationships with team-mates.
“The hat-trick was good for me,” he said. “The start was a little difficult because I only trained with the team for five or six days, then played the first game right away. It was also a very big step for me to leave my family and familiar surroundings. Of course, it takes time to get it right.”
The midfielder made his international debut in September 2018, and says he is remains patient in his quest to add to his eight appearances so far under Joachim Löw.
“In my two years with the national team, I have not been playing games but I’m still relatively young,” he said.
“I have much of games ahead of me which is the reason why so far I’ve always remained calmed. I have enough self-confidence to face the national team.”
