Lewis Hamilton and Serena Williams are committing millions of pounds to one of the bids vying to become the new owners of Chelsea.
Sky News can exclusively reveal the full line-up of investors backing the takeover offer for the club being spearheaded by Sir Martin Broughton, the former Liverpool and British Airways chairman - the most prominent of whom are the seven-times Formula 1 world champion and the former women's world tennis No 1.
Both Hamilton, who will compete for Mercedes at the Emilia Romagna Grand Prix at Imola this weekend - and Williams, who has won 23 Grand Slams including seven Wimbledon titles, have become established investors in their own right in recent years.
Serena Ventures, the tennis star's venture capital fund, this week announced an investment in Opensponsorship, a British-based sports technology start-up, while Hamilton has backed a range of early-stage companies such as Zapp, the London-based rapid grocery delivery app.
Their involvement in the Chelsea auction is unexpected - not least because Hamilton is an Arsenal fan.
Hamilton and Williams have, however, been in talks with the group spearheaded by Broughton for several weeks.
