My problem with this type of article, even when there is no truth in it, is it re-writes the narrative, and spoonfeeds a version of events, that once it sticks it is going nowhere.
The narrative is: we've been damn unlucky. With injuries, decisions, and goals not going in (part poor finishing, but part just luck, keepers making incredible saves, wrong side of the woodwork etc). Not: we've failed to win games because pep has tinkered.
So when we hit a period of consistency and wins and goals, and we will, it will become an accepted thing that pep tinkered the first half of the season, which cost us points, then the players told him to stop, and that made the difference.
This will be like the bloody 'sane has an attitude problem, his face is unhappy' bullshit line, say it enough and people will repeat it, and eventually beleive it.
