#1 Roman Abramovich (Chelsea) - £2bn investment
By far and away the biggest person or group to invest in the Premier League has been Roman Abramovich, who has poured a staggering £2bn into Chelsea since buying the club in 2003.
When the Russia oligarch, who started out as a street trader but built up a formidable portfolio due to smart investments, took over the club, they were a run-of-the-mill team in the middle of the standings, yet virtually overnight he transformed them into a world superpower.
Since then, he has led them to Champions League glory in 2011-12 and the Premier League title on five occasions.
They go into the 2017-18 season as defending English champions and are set to buy big once again this summer in order to relaunch a renewed charge on Europe.
