The 24-year-old is believed to be on Man United's radar, with the Red Devils preparing to move for at least one central defender at the end of the 2023-24 campaign.
Todibo was linked with a switch to Old Trafford at the start of this season, although a deal would only have been possible had Harry Maguire, who was strongly linked with West Ham United, moved on.
Man United could potentially be priced out of a deal for leading defensive target Jarrad Branthwaite, with Everton believed to value the Englishman in the region of £75m.
Todibo is also said to be on the club's shortlist, but according to Football Insider, senior figures at Nice are ready to block any attempt from Man United to sign the Frenchman.
Any potential move for Todibo from the English giants this summer would be complicated by the fact that INEOS own Nice and have now invested in Man United.
