World Cup 2018: 3 things Serbia got right in 1-0 win over Costa Rica

#2 Playing Sergej Milinkovic-Savic in an advanced role

Savic proved to be too hot to handle for the Costa Rican midfield

After the players were back on the field post the halftime break, Sergej Milinkovic-Savic was deployed in a more advanced role than the one he occupied in the first half. All of a sudden, Serbia's attacking threat tripled.

The Lazio midfielder was skiing past midfielders and defenders as though they weren't there at times. He also played Mitrovic into a one-on-one situation on two occasions but the striker couldn't finish off either of their chances.

Savic justified all the hype around him after having a stellar season at the Italian club. If he can continue to deliver similar performances and if Mitrovic can stop being so wasteful in front of goal, Serbia could become the dark horses of the tournament.
