RMC reports Kayode was denied a deadline day move to Amiens after the president of the French side filed the transfer documentation one minute after the deadline had passed.
Bernard Joannin had initially blamed a 'computing problem' for the debacle and despite making an appeal to the authorities the move was rejected.
Joannin has taken responsibility for leaving the deal so late in the window.
"Everything was recorded at 11.59pm, but FIFA received it at 12.01am.
“[Negotiations] are very complicated, except when your chequebook is out and you pay without talking. This was another discovery. We really learnt a lot, even if I ended the transfer window disappointed."
