Werder Bremen have no intention of withdrawing their appeal against the judgment by FIFA on Wednesday which obliges all clubs to release players under the age of 23 for the Olympic Games.
The Bundesliga club had already lodged a complaint to the Court of Arbitration for Sport (CAS), which was turned into an appeal when FIFA released its own findings this week.
And after receiving a written explanation from FIFA for their decision, Werder believe they still have a chance of overturning their decision.
'After examining the written reasoning for the decision of the single judge for the commission for the status of players, the management of Werder Bremen is of the opinion that nothing has changed factually regarding the issue,' read a statement from the club on Thursday.
'As was the case in the letter from the FIFA president two weeks ago, the decision of the judge is not in any way based on the current statutes in which it is clearly regulated in which conditions a club must release its players.'
The CAS has promised to deal with the matter by August 5 at the latest.
Werder and fellow Bundesliga side Schalke, who have also lodged an appeal, are in DFB-Pokal action just days after a decision is expected.
Both clubs still hope to have their players, Diego and Rafinha respectively, available for those matches
