Hamburg are willing to agree to Alen Halilovic's request to leave the club during the transfer window, according to sporting director Jens Todt.
Halilovic has not featured since the 3-0 Bundesliga loss to Hamburg in October and a report in his native Croatia claims Celta Vigo, Villarreal and Espanyol are all interested in bringing him back to LaLiga.
"Alen wants to play a lot more and he asked us for a change," Todt said, as quoted by Bild. "A loan is feasible.
"Winter transfers are the most difficult. Everyone is looking for a fully integrated player who is 100 per cent fit, speaks German as well as possible and has played every game in the first half of the season."
The 20-year-old, considered one of European football's brightest prospects, spent a productive loan spell with Sporting Gijon last season before signing for Hamburg in a €5million deal in July.
Barca have the option to buy Halilovic back for €10m during the first two years of his contract with the German club.
