#4 Virgil van Dijk
Virgil van Dijk is hot property right now, with a host of top clubs looking to win his signature. Liverpool looked the front-runners in the summer but now it seems it'll boil down to a tug of war between Chelsea and Manchester City.
While he definitely will not come cheap, Chelsea can more than afford the Dutch player by offloading David Luiz, who has apparently gathered interest from Real Madrid. If indeed David Luiz leaves the club, Chelsea should absolutely look to rope in the Southampton defender.
With Gary Cahill in his twilight years, 5 defenders in Azpilicueta, Christensen, Rudiger, Zouma and Van Dijk vying for 3 spots from next season sound terrifying for most opposition attacks.
