Kai Havertz has admitted the Premier League is much tougher than the Bundesliga after a testing Chelsea debut on Monday night.
The 21-year-old, a club record-signing this summer, was handed a start in the 3-1 win over Brighton at the AMEX, but it was clear he will need some time to find his feet after having just arrived at Stamford Bridge.
"It was a very tough game, very difficult because I had long holidays and I came back and trained for five or six days with the team," Havertz said in the Evening Standard.
"More important is that we won so I am very happy to make my debut.
"The Premier League is much tougher than the Bundesliga. I have seen that in training and saw it in the game as well. But I am happy to play 80 minutes and hopefully next week I will continue."
