A toothless performance from Les Aiglons at the weekend has their board apparently eager to sign the Italy international forward
Balotelli, unwanted by Jurgen Klopp at Anfield, reportedly met with Rivere to discuss a potential move.
Nice have made an impressive start to their league campaign, collecting seven points from their opening three games.
Speaking after their 1-1 draw at home to Lille on Saturday, Rivere said: "Do you have Balotelli's number?
"Call him and tell him we need a striker in Nice."
Balotelli, 26, spent last season on loan at AC Milan, but struggled with just three goals across 23 games in all competitions.
