The Chelsea Chronicle takes a look at the top 10 biggest transfer sales in Chelsea history, including former fan favourite Conor Gallagher.

The Blues are recognised as one of the clubs that reinvented the transfer market, with their exceptionally high spending under Roman Abramovich and now Todd Boehly and Co.

With that said, the Chelsea Chronicle takes a look at the most expensive transfer sales in Chelsea history.
