Sanchez, 25, is leaving Barcelona this summer as the Catalan giants look to totally rebuild their squad after a poor season by their standards, and, unsurprisingly, plenty of European clubs have been looking to snap up Sanchez, including Atletico Madrid, Juventus and Liverpool.
Yet it appears that he will this week join Arsenal in a £32m deal, providing the boost that the Gunners attack desperately needs having struggled to break teams down at times last season. Sanchez, along with Newcastle United right back Mathieu Debuchy, will become the club's first signings of the summer as Arsene Wenger looks to build on their FA Cup final win over Hull City.
Whilst replacing Bacary Sagna and adding another forward were huge priorities entering the summer transfer window, Arsenal could be set to miss out on a player who would give them the edge they need in the title race.
For too long, the Gunners have been seen as brittle, lacking in bite and easily wilted by heavy pressure. They have been lacking a real nasty, aggressive defensive midfield player who can protect the back four and allow their attacking players to flourish for some time, though Mathieu Flamini filled in this role well last season.
A perfect solution to this problem would be land Sanchez's international team mate Gary Medel, who appears set to join Inter Milan from relegated Cardiff City. The former Sevilla man, 26, is an expert at breaking up play, and his energetic style in front of the back four makes him an intimidating figure to try and beat.
He may not be the big name signing that Arsenal fans are looking for, but Medel is the perfect fit for what Arsenal need. He would happily sit and protect Laurent Koscielny and Per Mertesacker, whilst allowing the likes of Aaron Ramsey, Mesut Ozil and of course Sanchez to attack.
Sanchez may be able to put in a good word for Medel, but they may be too late to land him. Even if they do, he's the kind of player Arsenal need in order to really grind out results when the going gets tough - and that's key for a title challenge.
