Roman Abramovich celebrated his ten-year anniversary as owner of Chelsea Football Club earlier this year. The Russian billionaire has been held up as the man who changed English football, for better or worse, with his free-spending ways.
The BBC have done their sums and worked out that Abramovich has spent a total of £683.75 million on players in the last decade. His wealth has had an impact on the prices he has paid for a few players, as selling clubs know that they can hold out for a few million more, and that has certainly led to some questionable decisions over the years.
However, for every £50 million striker there have been one or two players who have provided value for the money that has been spent on them. Let's take a look at the top ten value-for-money transfers that Abramovich has made.
Value has been calculated by finding the difference between the initial transfer fee and the sell-on price of each player (if applicable.) That differential figure has then been divided by the number of appearances made, goals scored* and trophies won at the club.
