The Reds are thought to be leading the race for the Dutchman, with the Daily Mail claiming a part exchange deal is being considered.
He has since been linked with a move away from the club as a result, with several Premier League sides interested in him.
Liverpool, Everton and Tottenham Hotspur are all allegedly keen on his services, with the Reds believed to be leading their rivals at present.
