The 22-year-old has been involved on a regular basis since his arrival in Turin two years ago, the centre-back making 76 starts and seven substitute appearances.
However, according to Calciomercato, the Netherlands international would not say no to moving to Barcelona at the end of the campaign.
Despite having a release clause in the region of £135m, the Italian giants would not hold out for that fee should the player signal a desire to leave in 2022.
The player, who cost £67.5m in 2019, has just under three years remaining on his contract. body check tags ::
