1. FC Union Berlin midfielder Felix Kroos has joined Eintracht Braunschweig and brings an end to a four-and-a-half-year relationship with the Köpenick club.

The 29-year-old's contract came to an end this summer and he will join the 2.Bundesliga club. Tomorrow against Nürnberg, he will receive an official farewell from the club at half-time.

Union secured Kroos' services from Werder Bremen in 2016 after an initial six-month loan went well. The midfielder played 95 games in his first three years in Berlin and captained the team for two seasons. In 2018-19, Union earned promotion to the Bundesliga and Kroos played an important role in Urs Fischer's squad. He featured 15 times in last season's top-flight campaign, taking his overall record in Köpenick to 116 games – with eight goals scored.

"For four and a half years I was allowed to play in red and white. We have survived difficult phases, but above all we have made history and celebrated huge successes together, especially in the last two years. I will never forget that and it will remain the greatest success of my career! From the first to the last second, I identified myself 100% with the club and lived it - both on and off the park. I would like to take this opportunity to thank all my team-mates, coaches, coaches and also all other employees of the club for the journey together and I'm already looking forward to every single reunion here," said Kroos.

"Felix has made a great contribution to the positive development of our team both on and off the pitch in recent years, and we are very grateful to him for that. After the end of last season, we openly discussed whether and how things could continue for him at 1. FC Union Berlin, since Felix is a guy who is basically good for any team. At the moment, however, we are so full in midfield that we couldn't make him an offer. We would like to thank Felix for his commitment and wish him all the best with his next club in Braunschweig," said Oliver Ruhnert, Director for Professional Football at 1. FC Union Berlin.
