Chelsea spent £47.5 million to bring the Germany international from Leipzig in 2020.
But the 26-year-old has struggled since his arrival in English football, netting a disappointing 23-goal return in his 89 appearances for the Blues.
Chelsea have now decided to sell the striker back to Leipzig, according to transfer expert Fabrizio Romano.
“Leipzig is ready to take over Timo Werner from Chelsea, here we go! We have been told it will be a permanent deal and NOT a loan. Werner will be leaving Chelsea,” Romano tweeted.
“First call @Plettigoal today, now final details are discussed – it’s done, personal terms have been agreed since 1 month.”
Chelsea have already given Romelu Lukaku permission to leave Stamford Bridge this summer, and the Belgium international will return to Inter Milan for a season on loan.
Should Werner also leave, Thomas Tuchel would be left with just two senior strikers in his squad, Kai Havertz and Armando Broja.

“There was not a lot of demand for the number nine. Players sometimes want to change numbers, but surprisingly no one wants to touch it.
“Like, anyone taller than me in the club tells me ‘you know he had the nine and he didn’t score and he had the nine and he didn’t score either.’ Now we have a moment, nobody wants to touch the number nine.”
