The French midfielder moved to the La Liga side from Stoke City in 2016, leading to his international debut the following year.
Amid speculation that the 29-year-old could leave for Arsenal this summer, N'Zonzi has hinted that he could move on from Sevilla in the future.
"I am feeling very good at Seville but they are not the biggest club in Europe," N'Zonzi told reporters at a World Cup press conference.
"Playing with high profile players in a big team could be a good progression for me. We all know that the transfer window is open but we don't talk about it that much.
"There is a big tournament coming up and changing teams is not the main worry in the group."
N'Zonzi's France will play Australia, Peru and Denmark in Group C of the World Cup this month.
