Manchester United boss Jose Mourinho is tracking Benfica winger Andrija Zivkovic.

O Jogo says Mourinho has dispatched United's scouts to watch Benfica starlet Zivkovic.

Officials from the Red Devils were at the Portuguese side's Champions League opener against CSKA Moscow, with the 21-year-old providing an assist in his side's 2-1 defeat.

Scouts from Old Trafford have been present at every one of Zivkovic's appearances this season.

The Serb claimed three assists last season as he broke into the first team.
