Yep. We Chelsea fans have expericend it before. Happened between us and Spurs with Luka Modrić if I recall correctly, too.
Everton are probably thinking to themselves “this lot payed £80m for Harry Maguire. Why would we sell for significantly less than that?”
And that was years ago before the truly insane transfer fees of the last 3 years started popping off. He’s their biggest young talent. It would be like one of the big clubs going to Palace and offering £35m for Adam Wharton. Would probably take 70 for them to sell now.
