Real Madrid Deal potentially worth €150m

The most valuable shirt in the world

Real Madrid have opened negotiations with sportswear company Under Armour as the American franchise looks to break into the European market.

Los Blancos have been linked with an extension of their lucrative deal with Adidas as the German manufacturer are keen to see the club sign on until at least 2020.

As such, the Estadio Santiago Bernabeu club have reportedly told Under Armour that they could part ways with Adidas, who has sponsored them since 1998, for a deal worth at least 150 million euros a year.

The organisation, which began in 2006, has been sponsoring some of the world's biggest sports stars including Stephen Curry, Tom Brady, Jordan Spieth, Andy Murray and Michael Phelps.

The US manufacturer has also been providing Tottenham Hotspur's kit since 2011.

The potential deal with Real Madrid would make the highest paid club in the world with Manchester United currently earning 95m euros a year plus incentives with Adidas whilst Barcelona bring in 85m euros on their Nike deal.
