Arsenal are set to lose Nacho Monreal in the summer.
The versatile defender, who can play left back and centre-back, will be out of contract.
News had circulated in January that Arsenal would extend his deal be a year, exercising a club option.
However, Spanish publication Sport claims the former Osasuna man wants a return to his homeland.
