Top 10 most expensive Chelsea signings of all time
Chelsea has become one of the biggest clubs in football thanks to a trophy-laden decade and a half under Russian owner Roman Abramovich.
The Blues have left behind their mid-table status and are now one of the biggest spenders in world football - thanks to the deep pockets of the Russian oligarch.
The Stamford Bridge outfit have never looked back since the Roman empire began in London and have spent huge sums of money on players the 'boss' deemed fit for Chelsea.
#10 Antonio Rudiger
Rudiger was not the first choice for Blues boss Antonio Conte as the Italian wanted to sign then Juventus defender and now AC Milan skipper Leonardo Bonucci - but the former Azzurii boss was once again left disappointing as he had to settle for the second-best.
However, Rudiger has made a name for himself playing in a three-man defence at Roma so it did not take him long to fit-in at Chelsea and with him being just 25 right now, the initial £29 million Chelsea spent on him could look to be a bargain.
Rudiger has been consistent since joining the Blues and is expected to be a part of Chelsea's team for a long time as the Blues look to build a team for the future.
