Virgil van Dijk could take Southampton to the ‘arbitration board’ to complain of unfair treatment if still in the Netherlands.
De Telegraaf have reported - via Sport Witness - that the defender could see his wage rise from €2m per year to €8m per year if he moves to Liverpool, who are believed to have rekindled their interest.
The Dutchman had his head turned by interest from the Reds, and has now been banished from first team training by manager Mauricio Pellegrino.
Van Dijk has also been left out of the club's squad for a training camp in France this week, amid claims from Pellegrino that he is "not 100%" mentally.
If still in the Netherlands, Van Dijk would be able to complain about the treatment he has received, although the same would not be possible in England.
The 26-year-old may have to simply wait until the dispute between Southampton and Liverpool - which started after accusations that the Merseyside club had tapped up Van Dijk - are resolved.
De Telegraaf claim that if a deal is agreed for the Netherlands international, his transfer could cost double that of the current Dutch record held by Marc Overmars’ €40m move to Barcelona.
Van Dijk made 21 Premier league appearances for Southampton last season, as well as featuring six times in the Europa League.
