New Chelsea midfielder Kai Havertz has revealed that he has found life in the Premier League 'difficult' so far.
The German ace sealed a move to the Blues in the summer from Bayer Leverkusen for the princely fee of £72million.
The 21-year-old is yet to score in the Premier League and has registered one assist in four appearances - but has got off the mark for the club in the Carabao Cup as he scored a hat-trick against Championship side Barnsley.
The German international believes his career in west London has gone fairly well so far but admitted he struggled to get to grips with the English top flight at first.
