Manchester United boss Jose Mourinho was in Austria last Friday to assess Eintracht Frankfurt and Serbia winger Mijat Gacinovic.

The 22-year-old winger has netted twice in his first three international appearances for Serbia and played 87 minutes in his side's 3-2 defeat in World Cup qualifying last week.

The Mirror say Mourinho may face competition if he is to try to sign Gacinovic, with Bayern Munich interested in a move while Arsenal have also scouted him on the international scene.

The United boss was spotted in the crowd on Friday trying to go unnoticed in a grey cap and it was wondered whether he was keeping tabs on his own midfielder, Nemanja Matic.

Austria defeated Serbia 3-2 on the night, with Matic scoring Serbia's second. They responded to that loss with a 1-0 win over Georgia on Monday, which clinched top spot in Group D and their place at next year's World Cup in Russia.

Gacinovic has been at Frankfurt since 2015, when the German club signed him from Serbian side Vojvodina after he scored 11 goals in 10 games in the Super Liga.

He has found goals harder to come by in Germany, netting four times from 51 appearances in all competitions for Frankfurt.

One of those strikes has come this season, in their German Super Cup in the 3-0 win over TuS Erndtebruck.

He has one goal in nine matches for Frankfurt so far in 2017-18.
