The 36-year-old has been in good form for Juventus this season, scoring 28 goals in 32 Serie A appearances for Andrea Pirlo's side, but his future is in doubt with only one season remaining on his contract at the Old Lady.
Juve are at risk of missing out on a Champions League qualification spot for next season as they currently sit fifth in Serie A with just two games to play.
In a video filmed by a fan at a street celebration, Ronaldo's mother Dolores said: "I'm going to go to Turin and speak to him. Next year he will play in Alvalade, I'll convince him and he will return."
Ronaldo came through the academy system at Sporting Lisbon and made 31 senior appearances for the Portuguese side before making his move to Manchester United in 2003.
The stalwart attacker joined Juve in 2018 and has scored 100 goals and registered 22 assists for the club. body check tags ::
