I don't mind people criticising, the only thing that annoys me is the really aggressive, definitive proclamations. I think it's clear he's not at his best since the lockdown, but for some reason, people feel the need to say after any bad game he's never, ever going to be good enough, we were mugs for buying him, he needs to be sold, how could Pep ever drop Aguero for him etc. etc.
People just need to chill out a bit and critique what's going on in the present without deciding it's got to be extrapolated out forever and improvement isn't possible.
