The 23-year-old Senegal international has recently been linked with a move to the Spanish side.
“There are not many people in the world of football who could say no to Sevilla,” he said.
“It is a great team with great history.
“We are focused on the last league game with Wigan, life is at stake.
“I have one more year and I do not know what will happen or if I’ll renew my contract.”
