Usmanov also, in a swipe at the Gunners' transfer policy, accused manager Arsene Wenger of "building a team" for his rivals.
"I like many footballers, and I'm in contact with some of them. Perhaps my favourite of the last 10, 15 years is Thierry Henry. He's pushing me to buy all of Arsenal's shares, but I cannot predict the future," Usmanov told L'Equipe.
"The greatest achievement of Arsene Wenger is to have created two teams: the one that now plays for our rivals and the one that is trying to be among the best in the Premier League.
"That's why I say it's not enough to merely flatter the coach but to give him the possibility to buy the best players, superstars. But not just stars but those chosen by Wenger.
"It's unthinkable that the shareholders get well-paid while, for small clauses in contracts, we lose key players, symbols like Robin van Persie, Mathieu Flamini or Patrick Vieira. We should have increased their salaries when they started to be courted, started to look elsewhere. I don't know why we didn't propose that to them."
