Roman Abramovich’s time as Chelsea owner has been a huge success.

The Russian billionaire has owned the west London club for 18 years now, winning 16 trophies in the process.

His significant investment in transfers and Chelsea’s top training ground Cobham have helped propel the Blues into one of Europe’s biggest clubs.

During Abramovich’s time at Stamford Bridge, the club spent more than £ 2bn in transfer fees, more than any other England team.

This type of investment could only be made if Abramovich’s net worth was one of the largest in the world, confirmed by the Rich list recently published by the Sunday Times.

Abramovich has climbed four spots from last year’s list and now sits eighth on the list with an estimated fortune of £ 12.1 billion from his oil and real estate empire.

He is joined in the top ten by Alisher Usmanov, who held a substantial stake in Arsenal until 2018, when he was acquired by American Stan Kroenke.

David Sullivan, who is the current co-owner of West Ham, sits at number 162 on the list, dropping 27 places after his fortunes were eroded due to the financial implications of the pandemic.

The Welshman is joined by his son Jack, who was West Ham United women’s general manager from 2017 until earlier this year.

His previous role made him the youngest football executive in history as he started the job at just 17 years old.
