Not really controversial but imo not entirely accurate either. For example:
"when Pep goes and we change the way we play, I think he will have to go too", We don't know when or if Pep goes and why do you assume when he goes we change our system, when it is a model system for all our teams from kids upwards and is being copied by more and more clubs and national teams.
"How many of those saves Ortega made last night would Ederson have conceded? We'd have drawn, or even lost, that game." Wrong answer, it is speculative, no mortal being can foresee what would have happened just to try to validate their own opiniona. It is human nature to be be aware of competitors for their place no big deal if commentators to make a comment like that when a second choice player plays so well.
