De Laet returned to Antwerp in the January transfer window on a loan deal for until the end of the season.
According to HLN, the Belgian club find the transfer fee of securing the services of De Laet on a permanent contract too high.
It has also been reported that De Laet is willing to take a pay-cut from his €1.5m-per-year (£1.31m) salary, but there is still a gap between what the 29-year-old defender wants and what Antwerp are able to pay.
