It has been reported that Manchester United have Serbian young gun Marko Grujic in their sights.
The Daily Mail suggests that the Red Devils are containing to watch the 19-year-old Red Star Belgrade midfielder closely.
United sent scouts to watch Grujic in action in the local derby against FK Rad Beograd last weekend and saw him deliver a stunning 30-yard goal in a 3-0 win.
Grujic has been likened to Chelsea star Nemanja Matic and is also a potential target for the Blues who have close ties to the Serbian outfit.
