Arsenal investor Alisher Usmanov is set to be included in an investigation by BBC's Panorama series into Farhad Moshiri's Everton takeover and their 2007 purchase of a stake in Arsenal.
The Uzbekistan-born billionaire, who has attempted to rival the Gunners' majority shareholder Stan Kroenke for control of the club, does not directly have a stake in Everton.
But in a two-part series aired on Sunday and Monday night, Panorama will will focus on Usmanov's ties to friend Moshiri, with whom he set up Red & White Holdings, the holding company that they used to buy a 15% stake in Arsenal in 2007.
Football.London reports that despite owning a 30% stake in Arsenal Usmanov has no real power at the Emirates and has been blocked from gaining or exerting any internal influence by Kroenke and his company, Kroenke Sports Enterprise, which holds a majority of 67% over the other shareholders.
Usmanov's inability to have any effect within the the club has only made him more determined to portray himself as a potential saviour to supporters, although there are concerns within the fan base over the source of his wealth and business history.
According to the Times, the BBC's long-running current affairs programme claims to have documents that show that Usmanov bought the shares and gave half to his partner as a gift, leading to questions over how the Iranian funded his purchase of Everton in February 2016.
Since taking over at Goodison Park, Moshiri has presided over a record-breaking summer for the Toffees, during which they broke their club record for money spent in a single transfer window, and announced plans for a new stadium on Bramley Moore Dock, on the banks of the Mersey in the centre of Liverpool.
If Usmanov is behind his friend's investment in Everton then he could be in breach of Premier League regulations that state any shareholder with a 10 per cent stake in one club cannot buy into another.
Further suspicions over their arrangement were reportedly raised after Usmanov's company announced a sponsorship deal with the Toffees back in January, although both the club and representatives for the Russian industrial magnate denied any wrongdoing when they were approached by the Times.
