Las Palmas have announced the signing of Alen Halilovic from Hamburg on an 18-month loan deal.
The 20-year-old Croatia international only moved to the Bundesliga from Barcelona in July but has struggled to settle in Germany and has not played since October 21.
The attacking midfielder has now returned to La Liga on a temporary deal, although Las Palmas have an option to make the move permanent should he impress in Gran Canaria.
