Barcelona reportedly have a first-option clause to sign Atletico Madrid's young midfielder Saul Niguez.
Saul, 21, has made 29 appearances in La Liga for Barca's title rivals Atletico and hit the headlines this week by scoring a solo effort in the first leg of the Champions League semi-final against Bayern Munich.
According to Sport, Barca have first option to sign Saul as part of the deal that took David Villa to Atletico in 2013.
Saul is under contract at the Vicente Calderon until 2020, but there is a €60m (£47m) release clause in his contract.
