Santi Cazorla has been given a one-year contract by Villarreal, sources close to the La Liga side have told ESPN FC.
The 33-year-old midfielder has agreed a one-year deal with an option to extend it for a further season.
Villarreal will make an official the announcement at what they called a "stellar" presentation at their Ceramica Stadium on Thursday.
Last month, former Spain international Cazorla played his first game in 21 months since sustaining an Achilles tendon injury.
Villarreal coach Javi Calleja, reported to have been impressed by the dedication shown by Cazorla, said last month: "If everything goes according to plan and there are good vibes, Santi will be a luxury reinforcement for us."
