French club Nantes have demanded payment from Cardiff City over the £15m transfer of Emiliano Sala, BBC Wales has learned.

Sala, along with pilot David Ibbotson, was on board the Piper Malibu N264DB which lost radar contact near Guernsey on 21 January.

The Argentine striker, 28, was Premier League club Cardiff's record signing.

Cardiff have withheld the first scheduled payment until they are satisfied with the documentation.

BBC Wales has learned the transfer fee is due to be paid in instalments over three years.

It is understood Nantes are threatening legal action if they do not receive a payment within 10 days. The BBC has attempted to speak to Nantes for comment.

A source at Cardiff says they will honour the contract but not until they have clarified "all the facts".

It is unclear whether or not the club have insurance covering the cost of the transfer.

And Cardiff are "surprised" Nantes have made the demand while attempts are being made to recover a body from the plane that was carrying Sala and Ibbotson.

The body was seen in the Piper Malibu on Monday, two weeks after the plane vanished near Guernsey.

French club Bourdeaux are also entitled to a cut of the fee, thought to be 50% - Sala was on their books from 2012 to 2015 before joining Nantes.

The plane carrying Sala and Ibbotson, from Crowle, Lincolnshire, disappeared en route to Cardiff after the footballer returned to Nantes to say goodbye to his former team-mates.

The way I see it, Cardiff should keep 50%, and give 25% of the fee to Nantes and the other 25% to Bordeaux. The entire situation is fucked. I doubt they will find Sala, but if they do Cardiff should pay the entire fee as usual.

This is very bad timing IMO...

I agree with Amir, they are probably working out on a deal that can be swallowed by both sides next to this incident :(.

Red Card to those involved allowing this to be so public.

complete lack of class

reality of life: business >>>>> care for others

The world is funny as we always say ... Thinking about how to benefit from a dead person. Nothing is assured... Lol

Whole story is quite sordid at best.

Nantes président/owner will get the fee...

Buy some Gucci flip flops with that p

of course they have insurance. what kind of multi million dollar transfer doesn't have insurance

@Harlem see you have evolved from tolling the comment section
