Kelechi Nwakali will quit Huesca at the end of the season after he rejected a new contract tabled by the Spanish club.
The one-time U17 World Cup MVP could now move away from Huesca in January for a fee or be a free agent in the summer.
He has been linked with clubs in England and Spain.
The 23-year-old Nwakali has failed to strike it big in Spain since his permanent transfer from Arsenal in 2019.
In the second round of last season, he played on loan at Alcoron, where he scored four goals and helped the club stay up in the Segunda Division.
