The 28-year-old has been linked with a £25million move to Premier League side Manchester City.
Del Nido said in the Daily Star: “We have already discarded this opportunity because we feel that it will damage the team.
“We are involved in a lot of competitions and at the moment we do not want to lose such an important player.
“We are not interested in the money. I will not change my mind.
“Today Sevilla are not a selling club and the idea of winning matches is more important to us than money.
“The player and the agent have been told his. But the situation could be completely different in the summer.”
