Alen Halilovic has officially left Barcelona for Hamburg but the Catalans have the right to re-sign the Croatia starlet.
Halilovic was signed in the summer of 2014 from Dinamo Zagreb and spent 2015-16 on loan at Sporting Gijon, making 36 appearances, but Sport reports Barca have let him go for €5m.
Barca can re-sign the 20-year for €10m in the next two years, Sport add, and have the right of first refusal on the midfielder.
La Blaugrana have also confirmed the fee received for Halilovic and the buy-back price for the player who reportedly interested Valencia and Villarreal as well.
