Real Madrid have joined the battle for Atletico star Sergio Aguero.

Marca says Real want to secure a deal for the Argentina international in January to ward off rival interest from Chelsea, Manchester United and Manchester City.

Real are willing to go to £50 MILLION for Aguero, even if it means the young forward playing out the remainder of the season at the Vicente Calderon.

Atletico accept this will be the last season they have Aguero on the books and have already made a move for Lanus star Eduardo Salvio as a direct replacement.
