The Italian striker is behind Wayne Rooney, Javier Hernandez,
Dimitar Berbatov, Danny Welbeck and Michael Owen in the Old
Trafford pecking order.
Macheda was loaned to Sampdoria in January but failed to impress
during his spell in Serie A as the club were relegated from Italy's
top flight.
But although United boss Alex Ferguson is reluctant to let the
20-year-old leave on a permanent deal, he is open to farming him
out to a Premier League rival so Macheda can gain experience.
Macheda's agent Giovanni Bia said: "Macheda will not return to
Italy. Manchester United will send him on loan in the Premier
League.
"At this time, Newcastle have the edge over Queens Park
Rangers."
