Alaves have made a move for Stoke City midfielder Bojan Krkic.
Las Palmas and Malaga have also expressed interest in the 27-year-old, with the Spanish clubs keen to take him on loan.
Bojan was a major marquee signing when he arrived from Ajax in 2014, but his time at the bet365 Stadium has been punctuated by fitness issues.
He only started five Premier League matches last season.
