Manchester United assistant manager Mike Phelan has confirmed the club are keeping a close eye on precocious Dutch talent Ricky van Wolfswinkel.
The Sporting Lisbon starlet rose to prominence in the Eredivisie last season with FC Utrecht, sparking rumours of a move to the Barclays Premier League with both Liverpool and Arsenal thought to be keen.
However, the 22-year-old moved to Portugal, and his reputation continues to grow after six goals in six games for the Leões.
Phelan stated that the Red Devils have been monitoring the Holland international for years now, but would not commit as to if Sir Alex Ferguson was still considering a move.
"We have obviously known Van Wolfswinkel for a long time. He is a young striker, very talented, who has been growing in the last few seasons," Phelan told Portuguese newspaper Record.
"A club like Manchester United carefully follow many players all over the world."
United had great success with a Dutch striker at Old Trafford in the past, with Ruud van Nistelrooy becoming a club legend during his five years in Manchester. He scored 150 goals in 219 appearances in all competitions.
