Dundee manager James McPake says they have "done everything right at our end" to sign defender Zeno Ibsen Rossi on loan from Bournemouth.
The two clubs agreed a deal outfit prior to the closure of the transfer window on Monday but a technical issued meant the deal was not concluded.
Dundee hope Fifa will allow the deal to be completed.
"Our paperwork was in on time so hopefully we get a favourable one," said McPake.
"We've done everything right at our end. The English FA are backing it, the Scottish FA are backing it and we are thankful to them for that but we need to wait for a decision from Fifa.
