Dundee United will report Hull City to FIFA if the English club fail to pay the first instalment of the £2.85m fee due for Andy Robertson.

The Scotland internationalist moved from Tannadice last month, with the first £1m due to be paid by Hull last Friday.

However, United have still to receive the money, despite repeated assurances made by the Barclays Premier League club. It is understood that the Scottish Football Association have also contacted their English counterparts to help resolve the issue but without success.

United will take the matter to FIFA if Hull have still to pay the money by the close of business today.
