Real Madrid are considering a change from Adidas to Under Armour.
Under Armour currently supplies Southampton, Aston Villa and Tottenham Hotspur in England, as well as AZ in Holland.
Adidas has manufactured Real Madrid's kits since 1998 and their current deal runs through 2020. The two sides were close to reaching an extension last year but an agreement was never reached.
Real Madrid has reportedly told Under Armour that they would only leave Adidas for a deal worth $160 million per season.
