Nuri Sahin has joined Werder Bremen after Borussia Dortmund agreed to cancel his contract, which had one year remaining.
The 29-year-old has signed what is believed to be a two-year deal with Florian Kohfeldt's side, where he will wear the number 17 shirt.
"The talks with the owners and the coach were very good," he told the club's official website. "Werder are a big club, where you have the feeling something is growing. I'm looking forward to being part of it."
Kohfeldt said: "I don't think there's much more to say about the qualities of Nuri.
