Club Brugge have revealed that Everton will need to agree a new deal for Vadis Odjidja-Ofeo, if they want him in January.
The Toffees made a late move for the Belgian international on transfer deadline day and agreed a loan deal for the midfielder.
However, the paperwork was filed too late and FIFA refused to ratify the 23-year-old's move.
Now Brugge have said the situation is back to square one and if Everton still want him, a new deal will have to be agreed if David Moyes wants to pursue him further.
"The transfer window is now completely behind us and now the focus is back on Club Brugge," Brugge general manager Vincent Mannaert stated.
Mannaert revealed that the reason from Brugge's point of view, that the move collapsed was down to Everton.
"There are two facets to such a transfer. The first part concerns the administrative work: that was fine. The second point is an international transfer certificate and it went wrong.
"FIFA took seven days, but eventually there is no green light.
"We could have appealed to the sports tribunal in Lausanne, but we had little chance of success. Furthermore, we would again have had a long period of uncertainty.
"Now all parties know where they stand."
Mannaert dismissed claims that a deal for January was in place.
"There are no agreements or promises made about," said Mannaert.
"I can imagine that they will continue to monitor Vadis, but there are no guarantees.
"If Everton want Vadis in January, the negotiations will start from scratch."
Mannaert says the player is committed to Brugge again.
"We had a meeting and I had a good feeling. I'm sure Vadis will work hard to return to the level of last year.
"The uncertainty is gone and also the stress for Vadis has disappeared. That period is over and that's not coming back."
The player himself insists he is committed again to Brugge.
"I am glad that I can again focus on football," he said.
"I have had seven days to think, and that is more than enough - in the beginning I was very excited about the transfer to Everton , but now I am very happy to be in Brugge.
"I do not fell like Club Brugge has let me down, on the last day in England a lot of transfers happen and so it is hectic - but Club Brugge were very open with me on their communication and it worked well.
"Everton were just a little too later."
