The World Cup is not only football's biggest tournament, but it also serves as a shop window for players to impress onlooking clubs.
Arsenal are entering a critical transfer window, with the pressure building on manager Arsene Wenger. The Gunners secured their first trophy in nine years with a win over Hull City in the FA Cup final, but fans are hoping for a sustained title bid next season.
Their title bid fell apart in the second half of the campaign, and with plenty of areas of concern in the side, Wenger should be busy this summer. There's just the small matter of the World Cup to consider, and as we all know, players that impress on the world's biggest stage attract interest, so who could Wenger target from Group D?
Keylor Navas, Costa Rica
Emiliano Viviano failed to make much of an impact at the Emirates Stadium, and with Lukasz Fabianski set to leave the club this summer, Wenger will be looking to add competition for Wojciech Szczesny between the sticks. Navas has been tentatively linked with the Gunners having enjoyed a superb season in La Liga with Levante, and could now use the World Cup to make himself a household name.
Marco Verratti, Italy
Mikel Arteta had an underwhelming season and is now 32, so Arsenal may be looking to sign another holding midfielder this summer - and Wenger has been strongly linked with a swoop for Paris Saint-Germain's Italian international Verratti. The diminutive 21-year-old has been deemed as the long-term successor to Andrea Pirlo in the Italy national team, but with limited first-team opportunities in the French capital, he may become available.
Mario Balotelli, Italy
Olivier Giroud struggled to carry the workload on his own this season, so Wenger will almost certainly be looking to add another striker to his ranks this summer. Whilst controversial, former Manchester City star Balotelli has incredible ability and would seemingly be open to a move back to England having suffered racial abuse whilst back in Serie A with Milan - which has reportedly alerted Arsenal.
Martin Caceres, Uruguay
One of the biggest areas of concern for Arsenal is right back, where long-term incumbent Bacary Sagna is set to leave the club upon the expiration of his contract this summer. With depth also needed at centre back - whether Thomas Vermaelen departs or not - and Juventus defender Caceres as the positional versatility to play both roles. Earlier this season, it was reported that Arsenal were watching the former Barcelona man, and an impressive World Cup could trigger more interest.
Edinson Cavani, Uruguay
It's not often that Wenger splashes the cash, but he did last summer with the £42.5m capture of Mesut Ozil. With more money to spend this summer, there is the opportunity for another marquee capture, and with the Gunners needing to land at least one striker, PSG striker Cavani will almost certainly be on Wenger's list of targets, as the former Napoli man has been played out of position under Laurent Blanc.
