#2 Arsenal

Like Juventus, Arsenal have a lot of work to do in the transfer window. However, while the Italian champions need to rejuvenate, the London-based club simply need to bolster the quality of their squad.
Last season showed us more than ever that Arsenal are starting to lose ground on the other 'Top 6' sides. And the goalkeeping position is just one of many that need to be addressed.
The back four may be Arsenal's biggest construction site, but Petr Cech isn't getting any younger and David Ospina has proven countless times that he's not the most secure goalkeeper around.
If Arsenal truly want to restore their former glory, Oblak could be the kind of signing that could kick-start the Gunners' return to the top. Paired with some more defensive transfers, Oblak would provide Arsenal's free-flowing attack with more confidence in their backline.
Arsenal and Oblak could be a perfect fit, provided the Slovenian is prepared to ditch Atletico Madrid for a club that needs to rebuild a bit before regaining their status as a title challenger in the Premier League.
