The World Cup is not only football's biggest tournament, but it also serves as a shop window for players to impress onlooking clubs.
Manchester United's shocking season is finally over, and their fans can look forward to the summer with excitement. Manager David Moyes was sacked in April after a dismal ten month stint in charge at Old Trafford, and the announcement that Louis van Gaal will be the new manager has supporters looking forward with optimism.
Van Gaal must first complete his duties with the Dutch national team at this summer's World Cup, where he will get to see some of the finest talent around first hand. Some of those players on show could be potential targets for the former Bayern Munich and Barcelona coach, so here are five players in Group F who could be on United's radar.
Ezequiel Garay, Argentina
Former Real Madrid defender Garay has long been linked with United, but the Red Devils will now have to move quickly if they want to sign him as Bayern Munich have joined the race for his signature. The 27-year-old has been outstanding since signing for Benfica in 2011, and is expected to be the star of the Argentina defence at the World Cup this summer.
Enzo Perez, Argentina
Garay's club team mate Perez has made a late charge to break into Alejandro Sabella's Argentina squad, beating Ever Banega to a place in Brazil. With United needing midfield help, they are reportedly eyeing up a move for €30m-rated Perez, who has had a superb season in Portugal.
Angel di Maria, Argentina
From two current Benfica stars to one who left the club in 2010, di Maria has established himself as one of the top wingers in Europe during his time with Real Madrid. Yet with the Spanish giants looking to sign Real Sociedad's French winger Antoine Griezmann, di Maria has been tipped to leave the club this summer and with United desperately needing talent out wide, he should be on their radar.
Sead Kolasinac, Bosnia
Patrice Evra may have signed an extended deal to stay at Old Trafford, but United must look to land his future successor. Whilst Luke Shaw appears to be their primary target, Schalke's Kolasinac has been linked with the club recently and can play at both centre back and left back – versatility which could prove valuable for someone like van Gaal.
Miralem Pjanic, Bosnia
Kolasinac is joined in the Bosnia setup by midfielder Pjanic, who has had a superb season in Serie with Roma. Having racked up six goals and six assists for Rudy Garcia's men, Pjanic is one of the most highly rated midfielders in Europe, prompting speculation that United were looking at making a £25m bid for the former Lyon man – who is tipped to star in Brazil.
