Chelsea board member Eugene Tenenbaum has explained why Roman Abramovich bought the club in 2003, saying that the businessman loves challenges.
Abramovich took over the Blues with a £140 million ($175m) bid, kicking off a period of success for the club that has seen them win 16 major trophies in 17 years.
Tenenbaum, who is one of Abramovich's closest associates, explained that the Israeli-Russian billionaire was hungry for the challenge of taking an already-established football team to a higher level.
