The Gunners will be looking to build on the FA Cup final win over Hull City in May, where the club claimed their first silverware in almost nine years. In order to do that, manager Arsene Wenger must splash the cash this summer, and it already seems that Newcastle right back Mathieu Debuchy will join the club as Bacary Sagna's replacement.
Yet the area fans are hoping gets strengthened the most is in attack. Olivier Giroud struggled to carry the season-long workload on his own, and Wenger simply has to bring in more firepower – and his interest in snapping up Chilean international Sanchez would go some way to rectifying that particular problem. If Sanchez does arrive at the Emirates Stadium, it will be Wenger's second big money signing in the last year after the £42.5m signing of Mesut Ozil in 2013. The two are big name stars in European football, but can Sanchez's arrival improve Ozil's displays for Arsenal?
Ozil, 25, has endured a difficult time in England since his arrival from Real Madrid almost a year ago. Plagued by form and fitness issues throughout his first season in North London, Ozil became an easy target for the media, who often blamed the collapse of Arsenal's title bid on the occasional disappearing act from the former Schalke and Werder Bremen playmaker.
That was somewhat harsh, but Ozil certainly didn't have the impact Arsenal fans hoped for – and his performances at the World Cup with Germany have also been underwhelming, causing concern for Gunners fans who were desperate to see their marquee signing turn his form around away from the club ahead of the new season.
Yet the fact of the matter is that whilst Ozil certainly saw a drop off in form in the second half of the season, it coincided with the injury to Theo Walcott – one of the few options in the Arsenal attack that can offer pace in behind defences. After he suffered a season-ending knee injury in January, opposing teams could essentially stack the edge of the box without worrying about being caught out behind themselves – vastly limiting the outlets Ozil had at his disposal.
The arrival of Barcelona star Sanchez would give Wenger the ability to play him and Walcott either side of Ozil, and that combination of pace could well enable us to see a different version of the player that became a scapegoat for the club's struggles in 2014.
When he was at his best with Real, it was because of the pace around him in Cristiano Ronaldo and Angel di Maria, which gave Ozil space to create chances as defences were pushed back by the speed of Ronaldo and di Maria, and it worked to devastating effect for the Spanish giants.
It seems that Wenger has now realised that, and will look to put him in a similar situation next season - and we could ultimately see the player that we thought Arsenal had bought back in September.
