The crowded field to buy Chelsea now features 23-time Grand Slam winner Serena Williams and seven-time Formula One champion Lewis Hamilton. A long-standing fan of Arsenal, Hamilton has seized the opportunity to invest in its London rival as three bidders try to buy the Premier League club from sanctioned Russian owner Roman Abramovich. Williams and Hamilton are part of a consortium that features proposed investment from Josh Harris and David Blitzer, the owners of the NBA’s Philadelphia 76ers who would have to sell their stakes in Premier League club Crystal Palace to buy Chelsea.
