Atletico Madrid are in talks for a first signing ahead of the summer market.
Marca says Atletico are already making plans for next season and the upcoming transfer window.
One of the players on their radar is Luis Forcen, a 19-year-old striker whose contract at Real Zaragoza will expire in June.
Forcen is a U19 international with Spain and has already agreed to sign a three-year deal at Atletico.
The teenager had already been training with the first team at Zaragoza but will initially start off in Atletico's academy when he joins.
Los Rojiblancos also have their eye on two other Zaragoza youngsters in left-back Adrian Gonzalez and centre-back Daniel Martinez.
