Arsenal need to strengthen in both full-back positions ahead of next season. The lack of depth in this area of the field was a major reason why the Gunners failed to qualify for the Champions League towards the end of the last campaign as the opposition would target that area.
It seems Arsenal are already looking to improve at left-back, as according to The Athletic, Arsenal's priority is Martinez due to the 24-year-old's ability to play at centre-back and left-back. Martinez is reportedly keen on a move to the Emirates Stadium, and Ajax are rumoured to have rejected a bid in the region of £25million.
Despite looking to strengthen the left-side in the transfer market, Mikel Arteta will not need to do that for the right-hand side if he can persuade Hector Bellerin to stay at the club, as he would certainly be a better back-up for Takekiro Tomiyasu than Cedric Soares.
