You are absolutely unbearable. 'It's better to have nothing than a bad egg. ...' - are you Miguel de Cervantes?! What a bizarre aphorism.
I'm joking you're not unbearable
I see what you did there.
However you forgot to ask where he is from!
As far as Arthur goes for all the talk of his supposed partying, lack of professionalism and lack of stamina (I think that this was always a problem for him even when he played for Gremio, as he is one of the most unathletic players that I have seen), he never really was that spectacular other than being great at keeping possession. Despite that he was always a very lightweight version of Verratti with a far inferior passing range, eye for the final ball, progressive plays etc. Outside of a few good months at Barça, Arthur would struggle to make forward passes no matter the opponent and no matter if you held a gun to his face. Basically he was ”found” out as a fraud largely after a while. He had a decent Copa América for Brazil back in 2019 and he had a overall decent 2019 (until the fall even though he missed quite a few games at the end of the 2018-19 season if I recall) for Barça before he imploded. Bartomeu’s shenanigans to get rid of him were one of the few good things he did.
I was thus not surprised to see him fail at Juve. Never knew what Flopp wanted with him but whatever weakens Liverpool is always welcome news.
