The 64-year-old recently agreed to sell his 30% stake in the north London club to majority shareholder Stan Kroenke earlier in the month, with reports now linking the wealthy businessman to the blue half of Merseyside as a result.
Usmanov's USM Holdings already sponsor Everton's training ground, Finch Farm, while he has also discussed his friendship with the majority shareholder at Goodison Park, Farhad Moshiri.
"Should there be a proposal or a possibility to invest in them with good potential returns, I would consider the deal," he said, speaking to Bloomberg. "We are friends with Farhad Moshiri. If he needs the support, I am happy to help."
Usmanov arrived at Arsenal in 2007, after purchasing the shares of former vice-chairman David Dein, and despite being frustrated by the lack of influence he had at the club, saw the Gunners' value quadruple during his time there.
He continued, stating: "When I bought the stake in Arsenal I believed that football brands would be able to generate profit. This is happening now."
While Usmanov remains keen to stay in football, Kroenke is planning a compulsory buyout at Arsenal to seize the remaining shares at the club, once he has 90% of the stock, valuing Usmanov's shares at £550m, with the remaining shares at £52.4m.
Everton were one of the busier club's over the course of the recent transfer window, spending over £85m on new players, as the likes of Richarlison, Yerry Mina and Lucas Digne all came to Goodison Park for exceptional fees.
