Man Utd, Chelsea keep tabs on Dutch striker

Manchester United and Chelsea are both keeping tabs on Sporting Lisbon striker Ricky van Wolfswinkel.

United have been repeatedly linked with the 22-year-old Dutchman, but Chelsea have now entered the hunt, according to Metro.

Manager Andre Villas-Boas is expected to dispatch a scout to watch Sporting take on Benfica this weekend.

Van Wolfswinkel has scored nine goals in 13 appearances this season.
