They got to that position though as they were able to spend freely in the years after the initial takeover by AbramovichIt wasn't anything to do with the financials that they had to be sold last year, it was due to sanctioning of their owner. They have revenue of over 490m a year. For comparison, Everton has about 193m a year and Villa 184m a year. So every 3 and a half years or so they will have an extra Billion pounds in revenue to our clubs. Of course, they are going to have significantly more spending power.
There has to be limits on spending at some point because Chelsea are getting so much wrong in recruitment but they can just throw another £50 odd million at replacements until they get one right.
