Nantes have reportedly demanded the first instalment of the transfer fee for missing striker Emiliano Sala from Cardiff.

Sala completed a £15m move from the French Ligue 1 club to the Premier League side on 19 January but then he and pilot David Ibbotson disappeared when the plane they were travelling on vanished while en route from France to Cardiff on 21 January.

A private search discovered the wreckage of the plane, with one body apparently inside, off the coast of Guernsey on Monday and both men are presumed dead.

BBC Wales reported today that Nantes have given the Welsh club 10 days to pay the first payment of the transfer but that Cardiff were waiting until they had "clarified all the facts" before honouring the contract.

The club's insurance is believed to only cover around half of the total costs for the transfer, which would also include agent's fees and the player's salary over the course of his three-year contract.

A claim against the insurers of the Piper Malibu aircraft Sala and Ibbotson flew on is also possible, with Cardiff saying two weeks ago: "We are looking at the potential possibility of negligence that may have caused the accident."
