Chelsea paid £47.5m to sign the Germany international from Leipzig in 2020.
But the 26-year-old has struggled since his arrival in English football, making a disappointing comeback with 23 goals in 89 appearances for the Blues.
Chelsea have now decided to sell the striker back to RB Leipzig, according to transfer expert Fabrizio Romano.
“Leipzig are intent on signing Timo Werner from Chelsea, here we go! We have been told it will be a permanent deal, not a loan. Werner will leave Chelsea,” Romano wrote on Twitter.
“First contact with Plettigoal today, now final details under discussion – personal terms have been agreed 1 month ago.”
Chelsea have already allowed Romelu Lukaku to leave Stamford Bridge this summer, with the Belgium international returning to Inter Milan on a season-long loan.
Should Werner also leave, he would leave Thomas Tuchel with only two top strikers in his squad, Kai Havertz and Armando Bruga.

“The number nine has never been in great demand. Sometimes players want to change numbers but surprisingly no one wants to touch it.
“Like, anybody taller than me at the club says to me ‘You know he got the nine and he didn’t score and he had the nine and he didn’t score either’. Now we’ve got a moment, nobody wants to touch the nine.”
