Manchester United boss Louis van Gaal is keen to bring the best of his Holland squad to Old Trafford after the World Cup.
The Daily Mail says Van Gaal hopes Luke Shaw's transfer from Southampton can be wrapped up with the finer details of the £27million fee to be finalised.
However, scouts have also been busy compiling reports on members of his Holland squad for scrutiny by the club's hierarchy ahead of possible bids.
Feyenoord centre-back Bruno Martins Indi is one while his teammate Daryl Janmaat, the right-back, has also been watched.
Their club mate and fellow defender Stefan de Vrij has been linked with United but he is likely to sign for Lazio over the coming days.
A deal for Roma's Kevin Strootman remains on the cards once he proves he is recuperating well from his knee ligament injury.
