Fernandes missed out on a takeover of the Hammers himself earlier this week.
“I see West Ham as the unpolished diamond of the Premier League,” Fernandes told the Daily Telegraph.
“It should be a larger and more successful club than it is and so, when the chance came around again to buy it, I felt I could do it and fulfil an ambition.
“I have faith in [manager Gianfranco] Zola and the management team. It wasn’t their fault the club are in the predicament they are in and I genuinely believe Zola will be one of the managerial greats. I made no promises except West Ham would never again be in the situation it finds itself in now.”
Fernandes has been invited to invest in the Hammers by Sullivan, as a 50% stake in the club is still available.
“I would have to see whether they share the same vision, otherwise it could be a calamity for the club,” Fernandes said.
“You can only have one leader, one strategy. But I’m never one to say no to anything, especially as I’m very passionate about the club.
“On the positive side the club has a new owner and it has ended the uncertainty.”
