Fiorentina veteran Joaquin is open to returning to the Spanish Liga.
The 33 year-old has become a first-choice for Fiorentina coach Vincenzo Montella this season.
"A week before the season Montella said I wouldn't have many opportunities because of the formation," Joaquin told Cadena Ser.
"I just carried on calmly, thinking only about working to change the situation, and I succeeded.
"The future? I'm honest, and I wouldn't mind returning to play in Spain. Valencia, Sevilla and Malaga are three clubs where I was very happy."
