According to Sky Sports, Chelsea have agreed to pay the £45m fee to trigger his release clause.
He joins Hakim Ziyech as one of Chelsea’s new signings for next season.
An exciting future
Werner has had an incredibly impressive season with Leipzig.
In 43 games in all competitions, he has scored 32 goals and picked up 13 assists.
He is also the second highest goal scorer in the Bundesliga in this campaign, only five behind Robert Lewandowski.
'See you soon!'
In a post on Twitter, Werner said: “Really looking forward to playing for such a fantastic and historic club!”
He also filmed a video message and said: “Hey Chelsea fans, I’m very happy to join Chelsea next year and play at Stamford Bridge for you”.

Chelsea director Marina Granovskaia told the club website: “We are very excited that Timo Werner has chosen to join Chelsea.
“He is a player who was coveted all over Europe.
“We can’t wait to have Timo on board.”
Leading the line
Werner’s lightning pace and attacking movement has made him one of Europe’s top strikers.
Not only can he play as a striker but he is also capable of performing out wide.
Although his arrival will be hugely exciting for Chelsea fans and the Premier League, it raises questions about Tammy Abraham’s role in the squad.
The Englishman has scored 15 goals in 34 games this season and has been one of Chelsea’s finest players.
It will be interesting to see what Frank Lampard will do, whether he will look to play both of them up top or encourage rotation across all competitions.
Having scored last night against Fortuna Düsseldorf, Werner has just two games left for Leipzig before he makes his way to London.
Chelsea’s capture of such a prolific striker is another key moment in what is a very exciting time for the fans.
It will be interesting to see how Werner will play in the Premier League next season and if he can help guide Chelsea to more success.
