The Germany international made something of a quiet start to life at Stamford Bridge after having signed for the south west London side from Bayer Leverkusen under Frank Lampard last summer.
Havertz took some time to adapt to the rigours of English football and his performances improved as the campaign went on, and especially after the appointment of Thomas Tuchel as Lampard’s successor back in January.
The 22-year-old ended up scoring the crucial winning goal in Chelsea FC’s 1-0 win over Manchester City in the Champions League final last month after the Blues secured a top-four finish in the Premier League.
Germany legend Matthaus feels that it’s normal for a young player to take time to adapt to life in a new country and league, and he feels that Tuchel is the right man to get the best out of Havertz next term.
