Seven-time Formula 1 world champion Lewis Hamilton and American tennis player Serena Williams have joined Sir Martin Broughton’s plan to buy Chelsea, each of them ready to invest 10 million pounds, according to Sky Sports. The former British Airways boss, who spent a few months as president of Liverpool FC in 2010, has been in negotiations with the two stars for several weeks. According to the English channel, the Hamilton would play an important role, if the takeover project was successful, in promoting diversity and equality within the London club. In the past, basketball star LeBron James had also invested in the Premier League, being a shareholder in Liverpool for nearly a decade. Three projects still in the running for the takeover of Chelsea Since the withdrawal of the American consortium chaired by the Ricketts family, three projects remain in the running for the takeover of Chelsea before the deadline for submitting applications set for Thursday: that carried by Todd Boehly, co-owner of a baseball franchise – the Los Angeles Dodgers -, the one led by Martin Broughton, and the one initiated by Steve Pagliuca, co-owner of the Boston Celtics, in the NBA. Chelsea were put up for sale on March 2 by Roman Abramovich, who had anticipated British government sanctions targeting oligarchs close to the Kremlin and Vladimir Putin since the invasion of Ukraine. The club obtained a special government license allowing it to continue its activities, but under strict conditions.
