NAC Breda hopes to replace Jan van den Bergh with Rio Hillen. The club is trying to secure the 22-year-old defender from De Graafschap, as reported by Voetbal International. NAC doesn't seem to need to negotiate with De Graafschap because Hillen has a transfer clause in his contract. The transfer is expected to cost a few tons. Transfermarkt currently estimates his market worth at 600k euros.
