Chelsea have spent a ridiculous amount of money lately but they have it so why not. Their transfer ban was 3 years ago this summer, that gave them a substantial amount of leeway where ffp is concerned for the windows after it. They've got it to spend just as we have, just as united have and just as liverpool have even if they pretend they haven't.
They've spent it incredibly poorly though and will be in a real mess if they have another summer like the last 2. Paying that money for Fernández this early into his career is mental, he looks a great player that we should have got with alvarez in hindsight but the price now is insane, would us, or anybody else pay that kind of price for Alvarez off the back of the world cup if we hadn't already snapped him up last year?
I hope Chelsea get their act together (after this week) to me, they've always been the most tolerable club of the traditional top 6, I'd much sooner have them as our closest rivals than any of the other lot and whilst it now seems unlikely them pipping Liverpool and United to 4th would be superb.
