The World Cup group stage is over, and many players have caught the eye with their impressive displays ahead of the transfer window.
Group F was the tale of one giant and three hopefuls, as Argentina were dragged through the group by Lionel Messi, leaving Bosnia, Iran and Nigeria to scrap for second place. With one win, one draw and one defeat, it was Nigeria who went through to the last 16, following up their 2013 African Cup of Nations win with a decent World Cup campaign.
Unsurprisingly, Messi's heroics for Argentina have stolen the headlines in Group F, but with three smaller nations also in the group, it has provided a great platform for some unknown players to make names for themselves, such as Bosnia's Muhamed Besic and Nigeria's Juwon Oshaniwa – and Manchester United should look to target an unheralded star.
The Red Devils have already secured the signings of midfielder Ander Herrera and left back Luke Shaw from Athletic Bilbao and Southampton respectively, and whilst Shaw will no doubt be the long-term solution at left back after Patrice Evra's United career comes to an end, they could sign another young player who will help at left back and at centre back too.
Bosnia's Sead Kolasinac had been recently linked with a move to Old Trafford having impressed in Germany with Schalke, and established himself as a starter for Safet Susic's men ahead of the World Cup. The 21-year-old's campaign didn't get off to the best of starts as he scored an own goal in Bosnia's 2-1 defeat to Argentina, but he remained solid throughout the rest of the game.
He then missed the game against Nigeria before being reinstated against Iran, where he helped Bosnia claim their first ever World Cup win. His reputation is continuing to grow around Europe, and he appears to have a very bright future ahead of him.
There has been no word on how much Schalke would want in order to part with their young defender, but it's a question United should be asking as they ramp up their recruitment drive this summer. Capable of playing in the centre of defence too, he's a versatile player who can help United after Nemanja Vidic and Rio Ferdinand left the club at the end of their contracts, whilst also offering depth behind Shaw on the left hand side.
