Virgil van Dijk
Southampton centre-back Virgil van Dijk has been a talking point throughout the summer after his club reported Liverpool for reportedly approaching the defender illegally.
Despite his links with Liverpool, Arsene Wenger should look to pursue the 26-year-old in order to provide options in the centre of his backline.
With Laurent Koscielny slowing down, and skipper Per Mertesacker entering his final season with the Gunners, the squad are in desperate need of a strong authoritative figure.
The Dutchman will be able to provide the experience but will also be able to grow and develop at a bigger club, meaning the defender would provide a long-term solution for the Arsenal boss.
