Its immobility is glaring. Against the best like Haaland, Mbappe or Salah he will be too often in the decisive duels half a second too slow when they come up to him with speed. This has often been the case against other agile offensive players as well.
He is only fast on the route, but not in the first few meters. A Mbappe is long gone when Süle starts to pick up the pace.
In addition, there are always wrong assessments of game situations. For example, if he attacks, although it is better to hold the position in the situation, a space is then opened into which the opponent can then play a dangerous pass. Or he realizes too late that he has to attack.
Happened to the top IV of this world, too, but too often for him, for the demands that Bavaria has.
He is one of the good-very good BL defenders and his pure duel strength (in duel situations where there is little speed involved) is at a high level internationally, but as a total package it is not enough for Bayern in my opinion.
Here I see an Upamecano, whose qualities I have been convinced of in spite of the recent mistakes, and Hernandez as better options in the long term. And there will still be a Nianzou in the long term, maybe. a loan would be appropriate here.
