4) Serge Aurier (Toulouse to Arsenal)
Arsenal have been linked with a move for Toulouse and Ivory Coast right back Serge Aurier all summer, with the Gunners reportedly having agreed an £8 million fee with the Ligue 1 club for the player.
This would represent a bargain deal for Arsenal, who are required to replace experienced right back Bacary Sagna after he opted to join Manchester City on a free transfer this summer.
Aurier is an excellent, powerful full back who would be likely to take to Premier League football like a duck to water, making such a fee a fine investment.
