Manchester United boss Erik ten Hag has instructed their scouts to watch 12 Dutch players.
The United boss has already brought three players to Old Trafford from the Dutch top-flight in the form of Tyrell Malacia, Lisandro Martinez and Antony.
Ten Hag also has Dutchman Donny Van de Beek in his squad - who has now been joined by fellow Holland international Wout Weghorst.
One player who Ten Hag is particularly keen on is his former Ajax centre-back Jurrien Timber, says The Sun.
United tried to sign the 21-year-old defender over the summer and have been monitoring him since.
Timber's Ajax team-mates Devyne Rensch, 19, and Kenneth Taylor, 20, are also reportedly being lined up by Ten Hag.
It's understood that AZ Alkmaar winger Jesper Karlsson and PSV midfielder Joey Veerman - who are both 24 - are also being looked at by Ten Hag as potential recruits.
