LAUSANNE, Switzerland (AP) — Nantes has asked sport's highest court to overturn a one-year transfer embargo imposed by FIFA for signing forward Ismael Bangoura from Al Nasr.

In a counter move, the Dubai club wants the Court of Arbitration for Sport to increase the €4.5 million ($6.1 million) compensation FIFA ordered Nantes and Bangoura, a former Dynamo Kiev player, to pay for breaking his contract.

CAS said Thursday that all three parties have appealed FIFA's ruling, and verdicts are expected in "around four months."

"The French club and the player consider that the breach of contract with Al Nasr Sports Club was justified and that the sanctions should be lifted," the court said in a statement. "Al Nasr Sports Club also appealed to the CAS to request that the transfer indemnity be increased and the sanctions more severe."

The court expects to soon rule on requests by Nantes and Bangoura to freeze sanctions while the case is processed.

FIFA ruled this month that Nantes, which is second in the French second tier and chasing promotion to the top division, lured Bangoura to break his Al Nasr contract in January 2012. The Guinea international was playing at the African Cup of Nations that month.

Nantes has claimed that Al Nasr stopped paying Bangoura's salary and "deregistered" him before his move to France.

FIFA barred Nantes from registering players through to January 2014 and suspended Bangoura for four months. He has already served three months of the ban.

Bangoura spent just a few months with Nantes before being loaned to Qatari club Umm Salal.

The 28-year-old forward made his reputation in Kiev by scoring in home losses in the 2007-08 Champions League group stage against eventual winner Manchester United and Roma. He later joined Rennes in France before transferring to Dubai.
