Leaked footage from a meeting of Ligue 1 owners revealed American Textor, who is the majority owner of Lyon, was called a "cowboy" by the PSG chief.
The company failed with a bid to buy Everton last year, with The Friedkin Group led by fellow American billionaire Dan Friedkin completing a deal to buy a controlling 94.1 per cent stake in December 2024 worth in excess of £400m.
Textor accused Al-Khelaifi of being a "bully" and "tyrant", while Lens president Joseph Oughourlian also accused the PSG chief - also the chairman of beIN Sports - of having a conflict of interest.
CRYSTAL PALACE co-owner John Textor was seen wearing a cowboy hat as he hit back at Paris Saint-Germain president Nasser Al-Khelaifi following a bitter row.
The second was a far riskier idea to move the league to its own streaming service - a model Premier League bosses considered before signing a new record £6.7bn domestic television deal running for four years from the 2025/26 season.
