Clubs arranging transfer fees to help themselves is not evidence of an owner injecting money into his club by privately paying other clubs secretly to get more money into Chelsea. How would it even work? How's this Abramovic money getting to the other football club? Or is your theory he's bribing executives at top clubs round the world to make their clubs overpay?
Apart from that, why the fuck would he even do it? He's got enough billionaire friends with businesses he could slip money or a mansion to in return for a sponsorship that would be much more effective, and not require constant new arrangements with every club who might buy a Chelsea player.
You're a sensible poster but you've come up with a ridiculous theory that's really quite hypocritical considering how much offence you take to opposition fans or media having similar theories about City.
