One thing is for certain, Chelsea owner Roman Abramovich isn't afraid to splash the cash and back his managers in the transfer market.

With such funds available, Chelsea fans have been blessed to see some of football's leading stars pull on the famous blue shirt.

Throughout the Abramovich era, the likes of Didier Drogba, Ashley Cole and John Terry have graced Stamford Bridge. But even before the Russian took over the west London club, Chelsea supporters were privy to watching Gianfranco Zola, Gianluca Vialli and Marcel Desailly amongst many more.
