Southampton forward Juan Miguel Jimenez, better known as Juanmi, has signed for five years with Real Sociedad, the Spanish La Liga club said on Thursday.

"Real Sociedad have reached agreement with Southampton to sign forward Juanmi," the Basque club said, adding that the player had penned a deal until June 30, 2021.

Juanmi, 23, is heading back to the Spanish league after just a year with Southampton, where he signed a four-year deal in 2015 with a seven-million-euros release clause after previously spending five seasons at Malaga.

"It's a matter of pride to be part of an historic club, a big club with an exciting project and a great group," said Juanmi, who has twice won the European under-19 title with Spain.
