4. Hugo Mallo (Celta Vigo)
The recent additions of Santi Cazorla and Nacho Monreal at Arsenal suggest that Wenger is increasingly looking to Spain to source talent and the Frenchman will surely have taken note of Celta Vigo’s promising full-back Mallo.
The Spain under-21 international will turn 22-year-old this year but has been a regular for the La Liga outfit for the past three-and-a-half years.
Mallo loves a tackle and is technically good but is yet to provide an assist this season, a stat that may deter Wenger and his scouting team.
