Fernandes has only met Sheikh Mansour recently but is well aware of the Abu Dhabi billionaire's plans to transform the club into a European force.
"I have just seen Sheikh Mansour once, after a training session," he told the Daily Express. "He was wearing a suit rather than Arab robes. He just said one thing to us, 'Good luck'. But the Kaka affair is a sign that the Sheikh plans to take things to the limit. Everything is falling into place at the club. We travel in the best aeroplanes, and when we get off we check into the smartest hotels.
"I am now at the richest club in the world. It is a nice experience, but not an easy one to deal with.
"You can sense the impatience around the club. The fans are simmering with excitement, and dreaming of us deposing Manchester United.
"We lose some stupid matches. But we win others 4-0 or 5-0 thanks to our amazing attacking potential and, above all, thanks to Robinho. He is completely unpredictable on the pitch.
"He is just two years older than me, and we have become friends. We often have meals together."
