Pep didn't have him at Barca mate.
I agree with you, he was on a hiding to nothing from the start.
Some fans made their mind up before he even set foot on a pitch, others made their mind up after his performance at the swamp.
Others seemed to blame him for our defences inability to play out from the back and the groans were audible almost every time he had the ball at his feet, I can only assume that didn't help him settle.
Despite all that, he still performed pretty well for his first 10 PL games, his save percentage was at 74% at that stage ( before anyone gives me shit for stats remember how they were used as a stick to beat him with, fair's fair) but he was still being blamed for almost every goal we conceded.
It all went to shit for him following the Chelsea game, his form went completely and everything that came at him seemed to go in. At that stage he needed support imo, instead the number of dissenting voices grew and made the situation worse.
He's shown great character to bounce back this summer after all that. Like you say hopefully he can take that into next season with us and give Ederson the required competition and support.
