Chelsea splashed out £47.5m to sign the Germany international from Leipzig in 2020.
But the 26-year-old has struggled since arriving in English football, managing a disappointing return of 23 goals in 89 appearances for the Blues.
Chelsea have now decided to sell the striker back to Leipzig, according to transfer expert Fabrizio Romano.
“Leipzig set to sign Timo Werner from Chelsea here! We’ve been told it will be a permanent deal and NOT on loan. Werner will be leaving Chelsea,” Romano tweeted.
“First phone call today to @Plettigoal, now discussing final details – done, personal terms agreed 1 month ago.”
Chelsea have already allowed Romelu Lukaku to leave Stamford Bridge this summer, with the Belgium international rejoining Inter on a season-long loan.
If Werner also leaves, it would leave Thomas Tuchel with just two senior strikers in his squad, Kai Havertz and Armando Brocha.

“There wasn’t much demand for the number nine. Players sometimes want to change numbers, but surprisingly no one wants to touch it.
“Like, everybody who’s older than me at the club says to me ‘you know he had the nine and didn’t score and he had the nine and also didn’t score.’ Now we have a moment, nobody wants to touch the number nine.”
