Another possible candidate is Suleiman Kerimov, a Russian deputy and co-owner of oil company Nafta-Moskva, who failed in a £270million bid for Roma last year.
He also failed last year to buy Russian club Torpedo in a deal with Russian banker Alexander Mamut. Both Mamut and Kerimov are said to be close to Abramovich.
Zahavi also spoke in the interview about his role in the Chelsea deal. He said: "I was asked to find out the price of the club and almost immediately a decision was made.
"Roman Abramovich sees clearly what he wants and makes a decision without wavering, that's why it is easy to work with him."
