Balotelli 'ready to make financial effort' to stay in Nice

"I can tell you three things - one, he's a player who wants to continue with us; two, he's ready to make a financial effort; three, discussions are continuing," said Rivere.

"It's a complicated dossier," said a source close to the discussions, adding that the player could extend by two years with a monthly salary of 450,000 euros ($502,000).

Balotelli -- who played in Italy for AC Milan and Inter Milan and England with Liverpool and Manchester City -- joined Nice in 2016, with his 15 goals helping lift the team to third in Ligue 1 and a Champions League spot next season.

The 26-year-old could opt to stay in France and try to resurrect his international career with Italy for the 2018 World Cup finals in Russia.

Balotelli has scored 13 times in 33 international appearances, but hasn't played for Italy since featuring in a 1-0 defeat to Uruguay that saw the Azzurri eliminated during the group stages of the 2014 World Cup in Brazil.
