How did he make his billions? The son of Uzbekistan's deputy prosecutor-general, Usmanov was jailed in 1980 on 'trumped-up' charges of fraud, serving six years in a maximum security prison. Released at 33, he went into business making plastic bags. He then borrowed big to buy up former Soviet assets, rising up the iron-and-steel industry. He now owns the giant Metalloinvest Group and the influential Kommersant newspaper, and has stakes in steelmaker Corus and MegaFon, Russia's third-largest mobile network.
The secret of his success? A flare for the equity markets. He also keeps his nose out of politics, which puts him on the right side of Vladimir Putin, whom he describes as a 'blessing for Russia'. Relations with the Arsenal faithful have so far been rockier.
