Pogba was voted Premier league team of the season a year and half ago too, the only player from our squad who managed that. Yet he is now the worst player in our squad and nobody wants to see him play for us.
It’s not really only because of his inability to co-exist with Ronaldo that he’s struggled. Even in games where Ronaldo hasn’t featured, he’s been completely anonymous. Take the match against Barca just a few weeks ago for example. Perfect opportunity to take the mantle in Ronaldo’s absence but he did nothing. The game at the weekend, was partially responsible for Lazio’s late equaliser. He also had other embarrassing moments in that game. He’s too inconsistent for me to be labelled as World Class. I’d have him down as a very good player with a World Class ceiling if he got things going.
And for your second point, I don’t think it goes as far as Juve not wanting to offend him. Ronaldo had a very legitimate case for being Juventus’ best player last season and many believe he was. He scored the most goals for the team by far (breaking age old records) and was actually the difference maker in their most important games of the season (against Lazio & Lyon at home). I think it could’ve gone to either one of them.
Every player has such games, not even Ronaldo is an exception to that and even Messi is rather anonymous if his team is dominated. Dybala is easily a top 5 play maker in the world and has excellent output, last season as well. Ronaldo broke records, yes, but in large parts this had to do with penalty calls in Italy being all over the place. It's not normal for a player to score 12 penalties in Serie A. The same goals for Immobile.
I mean, if Dybala isn't world class I wonder who is. There are not many players in the world who are clearly better than Dybala right now. Especially since Dybala is proving it since years:
2015/16: 19 goals, 7 assists in 2463 minutes (94 minutes per scorer)
2016/17: 11 goals, 7 assists in 2153 minutes (119 minutes per scorer)
2017/18: 22 goals, 5 assists in 2354 minutes (87 minutes per scorer)
2018/19: 5 goals, 2 assists in 2137 minutes (305 minutes per scorer, this was the season Ronaldo joined)
2019/20: 11 goals, 11 assists in 2165 minutes (98 minutes per scorer)
All that on top of being one of the best play makers in the world. I find it hard to argue he isn't world class.
