Werder Bremen midfielder Serge Gnabry is leaving the club after just one season.
The 21-year-old Germany international moved to the Bundesliga from Arsenal in August but has triggered a clause in his contract allowing him to leave the Weser-Stadion.
"After a very good first year for him at Werder, Serge has informed us that he would like to take the next step in his career," managing director Frank Baumann told Werder's website.
"He will therefore activate a clause in his contract and leave the club at the end of the month."
Coach Alexander Houri added: "It's obviously a pity as Serge was a go-to guy for us, someone who has undergone a remarkable development and has helped the team enormously with his performances.
"We wish him all the best for the future."
Gnabry made 27 league appearances during his short spell at Werder, scoring 11 goals as Nouri's men finished eighth.
The midfielder also confirmed the news in a statement to Werder fans on his Twitter account, but was unwiling to disclose details of his next move.
"My path lies elsewhere but I will say more about this another time, " Gnabry wrote.
"Today, it's important for me to say thank you. I will keep you all in my heart."
