Rafal Gikiewicz will be leaving Union Berlin on a free transfer when his contract expires this summer.
Union Berlin will part company with Rafal Gikiewicz at the end of the season, the club have announced.
The parties haven't been able to reach an agreement on an extension of the goalkeeper's contract, which expires this summer.
"When this season is over, I will look back on two very special years here. We've been promoted and we already have 30 points in the Bundesliga on our books and good chances of retaining our status. I want to achieve this target with Union, then there will be a new club in my life and a new goalkeeper for Union," said Rafal Gikiewicz.
Union director of professional football Oliver Ruhnert said:
"Rafal Gikiewicz has left an extraordinary mark on Union and he is certainly a player with whom we associate extraordinary experiences and who we will remember long and fondly after this season.
"After several rounds of negotiations, however, we were unable to reach a financial agreement, so we decided to re-orient ourselves with regards to the goalkeeping position. First of all, however, we are concentrating together on the current season, which we want to bring to a successful end by retaining our Bundesliga status."
The 32-year-old made the move to Berlin from SC Freiburg in 2018.
