Roman Abramovich rose from a penniless background in Russia's frozen north to become a multi-billionaire and a celebrity football tycoon who transformed the fortunes of one of England's most famous clubs. But his empire was left teetering after Russia's invasion of Ukraine, which raised questions about his closeness to the Kremlin, as harsh sanctions began to be slapped on supporters of Vladimir Putin. As speculation swirled that he also could be targeted, he said on Wednesday he was selling Premier League side Chelsea "in the best interest of the club, the fans, the employees, as well as the club's sponsors and partners".
