Roman Abramovich, a Russian oligarch, said he planned to sell the English soccer club Chelsea FC.

A group led by the Swedish billionaire Hansjörg Wyss appeared to be an early front-runner.

US billionaires may up the ante for the club, which has an estimated worth of over $3 billion.

UPDATE: On Thursday, the UK government announced sanctions against Roman Abramovich, including the freezing of his assets. This means he is likely unable to sell Chelsea for the foreseeable future.

The race to purchase one of the biggest soccer clubs in the world is on, and a group of US billionaires is leading the pack.

Soon after the Russian invasion of Ukraine and the subsequent calls for the UK government to seize the assets of Russian billionaires, the Russian oligarch Roman Abramovich announced his intention to sell the English Premier League club Chelsea FC.

ESPN reported that Abramovich wanted at least $3.9 billion (3 billion pounds) for the club. Chelsea FC was valued at $3.2 billion in Forbes' most recent valuations of the top soccer teams. Abramovich became Chelsea's owner in 2003, purchasing its parent company for $230 million.

Below, we take a look at the people who reports say are interested in becoming the new owners of the Premier League powerhouse.
