Kai Havertz praised the impact Thomas Tuchel has had on his career, with the new Bayern Munich boss having coached the Germany international at Chelsea.
Tuchel, who was announced as Bayern coach following Julian Nagelsmann's surprise sacking last week, took charge of the Blues between January 2021 and last September.
The German led Chelsea to the Champions League in 2021, with Havertz scoring the winning goal by 1-0 over Manchester City, also from the Premier League.
Speaking to The Guardian about Tuchel's influence, he said: "Tuchel gave me a different idea of football.
"Every detail counts, every centimetre, how you touch the ball, how you control it, where you pass, which foot, movement, creating spaces: he is simply top-notch. To come and win the Champions League in six months says it all" .
