Internationally, he has been capped eighteen times for his country, scoring once, and was part of the squad that reached the World Cup final in Brazil last summer.
United boss Louis van Gaal is set to strengthen his defensive options this summer, with the former Netherlands manager having to call upon youngsters this season.
Tyler Blackett and Paddy McNair have racked up twenty-three league games between this this season, with both having made their debuts early into this campaign.
Chris Smalling has recently signed a new deal with the club, though the Old Trafford futures of both Jonny Evans and Phil Jones remain unclear.
