Emiliano Sala money transfer line rumbles after the revelation of Cardiff's registration

The dispute over the transfer of Emiliano Sala to Cardiff took a new turn after it appeared that his decision had not received the green light of the Premier League.

The Bluebirds refuse to pay Nantes as investigations into the transfer of the tragic striker continue, while FIFA is also studying the issue.

And the Premier League club has now discovered that it does not fully comply with the rules of the Premier League.

The Sun claim that Cardiff failed to comply with two specific transfer provisions when he filed the documents for his £ 15 million move.

This is despite the announcement of Cardiff's signature and announcement by the Premier League of movement on their website.

The report goes on to say that Sala would have been unavailable to play Cardiff until the problems were solved.

Argentina died when the plane that was transporting it from Nantes to Cardiff crashed into the Channel shortly after signing for the club.

His body was later found in the wreckage, while the pilot David Ibbotson is still missing.

FIFA is currently investigating the transfer of Sala de Nantes to Cardiff City following a complaint from the French club.

Cardiff City President Mehmet Dalman said the club would pay the £ 15m transfer to Nantes for Sala "if contractually required".

The clubs were involved in a dispute over when the first installment should be paid, although Cardiff City Manager Neil Warnock said last month that he thought Nantes had agreed to an extension.
