Ricky van Wolfswinkel is continuing to attract interest from Manchester United, despite maintaining he has no interest in leaving Sporting CP.
The Dutch striker only moved to Lisbon from Utrecht in the summer, and maintains he will honour his contract with his new club.
However, according to Portuguese newspaper A Bola, United are still monitoring van Wolfswinkel with great interest, and had scouts in attendance to watch 22-year-old on Sunday.
Van Wolfswinkel scored in front of United representatives against Feirense as Sporting triumphed 2-0 at the Estádio Marcolino de Castro.
Liverpool had previously been linked with van Wolfswinkel before he left Utrecht, while United are also thought to have a long-standing interest in the young forward.
However, it is since his summer transfer that United have made a more concerted effort to pursue van Wolfswinkel, and Sir Alex Ferguson's No.2 Mike Phelan has confirmed the club tracking him.
Meanwhile, the Holland international is also attracting interest from PSV Eindhoven, AS Monaco, Saint-Etienne, Sochaux and Parma, Genoa and Novara.
