Villarreal, Celta Vigo and Espanyol are all keen on bringing Croatian playmaker Alen Halilovic back to La Liga after a spell with Hamburg in Germany.
The 20-year-old joined the Bundesliga side in August following two years at Barcelona, which included a season-long loan spell at Sporting Gijon in the 2015-16 campaign.
Croatian sports daily Sportske Novosti are claiming the Spanish trio are all keen on adding the talented Croatian on a loan deal until the end of the season with the German club open to offers, with Halilovic only featuring six times and starting only once this season.
The former Dinamo Zagreb midfielder impressed for Barcelona 'B' in the Segunda before playing a key role in Sporting's survival in La Liga last year.
