Alejandro Pozuelo has departed Swansea City after just one season, leaving the club to join Spanish side Rayo Vallecano.
The Premier League team confirmed on Thursday that the 22-year-old attacking midfielder has returned to his homeland, moving to Rayo for an undisclosed fee.
Pozuelo joined Swansea from Real Betis on a three-year contract in July last year.
But the Seville-born playmaker struggled for consistency in his only season at the Liberty Stadium, scoring two goals in 36 appearances.
His final appearance for the club came back in February in a Europa League clash with Napoli, and Pozuelo has now become the latest Spaniard to leave Swansea as they rebuild under manager Garry Monk.
Pozuelo's departure follows that of Michu, who joined Napoli on loan earlier this month, and Alvaro Vazquez, whose loan from Getafe ended with Swansea opting not to activate their option to buy.
Pablo Hernandez and Jose Canas also appear set to leave the Liberty Stadium after they were left out of the club's pre-season tour of North America.
