Chelsea takeover: Lewis Hamilton & Serena Williams back Sir Martin Broughton's bid

Lewis Hamilton and Serena Williams are two of the investors backing the bid.

Three groups are in the running to purchase the club for 2.5 billion dollars.

Sky reported that seven-time Formula 1 champion Hamilton and 23-time Grand Slam tennis champion Williams have pledged investment into the bid.

Lord Coe is a supporter of the bid.

The Blues have a licence from the UK government.

The club was put up for sale byAbramovich before he was sanctioned for his alleged links to Putin.

Hamilton and Williams have been involved with the bid from the beginning.

They wouldn't have a say in footballing decisions.

The Rogers family, who are based in Canada and own media and telecoms company Rogers Communications, are among the investors in the bid.

Crystal Palace co-owners Josh Harris and David Blitzer are backing the bid, as are investment bankers Michael Klein and Lord Coe.

Todd Boehly and co-owner of the Boston Celtics are part of a group that is trying to buy Chelsea.

• Three bidders remain - but who is best placed?

Raine Group, an American investment firm, has been tasked with selling the club and the UK government is expected to issue a new licence, allowing the club to be sold once a preferred buyer has been identified.

The sale must be approved by the owners and directors of the league.

The decision about a preferred bidder is unlikely this week, but it is expected that there will be little opposition to any of the bids from the government or the league.

The FA Cup final will take place on 14 May and will see the winner face off against the runner-up.
