The clamour from Manchester United fans to sign Sergej Milinkovic-Savic is growing after he played a central role in Serbia's World Cup win over Costa Rica on Sunday.

With the summer tournament in full swing, fans of clubs from all over the world are casting a close look at the top performers and considering who they should and shouldn't be making a move for this summer.

Scouting at the World Cup could arguably be seen as risky, but it's often a great chance to see how players cope at the elite level under the maximum pressure possible.

One man that United fans would love at Old Trafford is Lazio midfielder Milinkovic-Savic, who they have been linked with consistently over the last few months.

Still just 23 years of age, he produced excellent form for Lazio last season before heading to Russia, scoring 14 goals from midfield in all competitions.

Is he the player to complete Jose Mourinho's midfield puzzle?

Fans took to Twitter after Sunday's performance to share their thoughts...
