It has been reported that Napoli president Aurelio De Laurentiis tried his best to convince Emery to accept a three-year contract, but he failed.
The 43-year-old former Valencia coach is now likely to remain in Seville, according to the report.
Sevilla have been claimed to have offered Emery a pay rise, and it seems that the Spaniard is happy with it and will carry on at the Ramon Sanchez Pizjuan.
The latest development will come as a blow to West Ham, who are keen on securing the services of the former Almeria boss, according to The Independent.
However, staying at Sevilla makes perfect sense for Emery. Los Rojiblancos have won the Europa League twice in a row under him and will feature in the Champions League next season - there is no reason for him to leave a winning team.
