The winger is set to go out on loan from Villarreal, but will still be in Spain's top flight.
Mexico international Javier Aquino is set to play for Rayo Vallecano in Spain’s La Liga next season.
The speedy winger has been loaned out by Villarreal for the 2014-15 season in La Liga, pending a medical, according to a brief statement on Rayo Vallecano’s website.
The move could be an attempt by Villarreal to free up one of its three available spots for non-European Union nationals.

Aquino joined Villarreal in January 2013 when the Yellow Submarine were still in Spain’s second division, and the 24-year-old helped the team to promotion, starting 18 games as the club finished sixth in its return to the top flight last season.
Rayo Vallecano ended up in 12th place in the 2013-14 La Liga season and leaked more goals than any other team in the league.
Oaxaca native Aquino started his career at Cruz Azul, helped Mexico to Olympic gold in London 2012 and was part of El Tri’s squad at Brazil 2014.
