Although i don't really like him, he's not at fault for Messi leaving. It's mainly Bartomeu's doing with a side of Tebas shooting himself and the league in the foot with these preposterous wage caps.
Nobody forced us to shell out 120m straight cash for him with 30-40m wage too boot. Even under those circumstances where covid wasn't wreaking havoc on global economics it didn't make sense to take a loan and pay his fucking release clause in one go. After just spending north of 100m in consecutive transfer windows the year before to make matters worse. Bartomeu and the rest of his cronies should be hanged in Placa de Catalunya for the disastrous way they left the club. People should direct their anger towards that gobeshit.
Besides, as underwhelming as Griezmann has been, he at least puts in the work 24/7 on that pitch and is available be it a snowstorm or 40 degrees celsius. It's the other bums who don't even try that are the ones who should be blamed more.
