As long as the paperwork was signed between the 2 clubs, the deal was done surely?
"A Cardiff source said the transfer agreement stipulated - at the request of Nantes - that the Football Association of Wales and France's Ligue de Football Professional had to confirm the registration to both clubs by 22 January, along with confirmation of the international transfer certificate being released.
The Premier League also had to clear the registration.
The Bluebirds insist the terms of the contract maintains that if any parts of that arrangement were not confirmed, then the deal would be null and void.
They claim:
- Ligue de Football Professionel had not contacted Cardiff either before or after 22 January.
- The FAW did not confirm with Nantes.
- The Ligue de Football Professional did not confirm with Nantes until 25 January.
It is thought the notifications clause was inserted because if the deal fell through, both Cardiff and Nantes would have had time to seek a new player before the January transfer window closed on 31 January."
That suggests that the paperwork wasn't completed within the legal requirements so could legally be non-binding. We shall wait and see if it is true i guess.
