Manchester United and Chelsea might be forced to wait until next month to discover whether Vitesse Arnhem will listen to offers for highly-rated midfielder Marco van Ginkel, reports the Daily Telegraph.
The 20-year-old Dutchman has been impressing at the European U21 Championships in Israel this month, during Holland's run to the semi-finals, with numerous scouts keeping tabs on the Eredivisie star.
Unbeknown to Van Ginkel, Jim Lawlor - chief scout at Manchester United - has been monitoring him closely, as David Moyes weighs up a bid to lure the £12million-rated man to Old Trafford.
However, the Premier League champions will face a fight to secure the player's signature, with Jose Mourinho also keen to entice him to Stamford Bridge.
Chelsea have a partnership agreement with Vitesse, having sent a number of emerging young players on loan to the GelreDome in recent years, and for that reason alone can be considered slight favourites to land Van Ginkel.
However, neither Chelsea or Manchester United will find out if they have been successful in their transfer pursuit until July at the earliest, after the player revealed he will postpone any decision regarding his future until he returns from a post-tournament holiday.
"My future? Now I have a vacation and I'll concentrate on that," Van Ginkel said. "After my holiday, we will see. Maybe.
"Manchester United? I didn't know (about their interest), but I have two more years at Vitesse. It is a club that is growing, so I'm also happy there."
With a contract at Vitesse that runs until 2015, Van Ginkel insists he is happy in his homeland, and with the Eredivisie outfit having qualified for the Europa League in 2013/14, he could well stay in Holland for another year at least.
