The whole discussion is just so self-evidently flawed. It's really depressing to see how media outlets add to it with pure clickbait nonsense. "Does Klopp have a point?" Sky sports asks, and then proceeds with graphics showing how many penalties have been awarded. As if you could conclude that if that's the case, then Klopp's got a point. No one seems interested in pointing out the roaring fallacies at the heart of the argument, which are these:
1. Why is the point being raised? The only answer to that is that there's an implication that somehow one team is being unfairly favored and another is being unfairly penalised. Otherwise, there is nothing to discuss. The reason this is being merely implied and not stated explicitly is of course that it is a claim that is impossible to substantiate, because it's bonkers and there is no proof whatsoever for it. And Klopp knows it.
2. Why would you expect teams to receive an equal number of penalties? There is no reason why that would be the case. A skilled team which spends a comparatively large amount of time inside the opposition box, and who tends to attempt passes and dribbles while there, will be fouled more frequently than others. And if there is no reason why there'd be an equal number of penalties, then an unequal number of penalties given is not an indication that something is amiss.
