Club Brugge defender Antolin Alcaraz is a £2 million target for Hull City.
The Sun says the Paraguay ace has caught Tigers boss Phil Brown's eye during the Belgian outfit's Europa League campaign.
But Brugge will not sell the 27-year-old unless the price is right.
Coach Luc Devroe said: "We are stronger with Alcaraz than without. A move is only possible if a very good offer comes in."
