According to AS, the player is joining the Spanish side on a one-year spell, and they will pay for a percentage of his wages.
The outlet says Nasri is arriving to replace Yevhen Konoplyanka, who left Sevilla to join German club Schalke 04 today.
Recent reports from France had already claimed Sevilla were in pole position to sign the Manchester City player. He was heavily linked to a move to Besiktas as well.
Earlier claims from Turkey said Besiktas had been told Nasri was pulling out of a move there because he’d decided to stay at Manchester City, they may be a little hurt now.
Pep Guardiola was said to have had a chat with Nasri, and though the manager didn’t promise him a spot in the starting team, he allegedly said the Frenchman would be in matchday squads.
