As someone who watches Bayern games on a regular basis, I'd say Sabitzer is a decent/solid player who can fit into any team. The problem with Sabitzer and Bayern is simply that Nagelsmann prefers Kimmich and Goretzka instead of him. While I do understand that Nagelsmann chooses Kimmich over Sabitzer, since the former is simply a better overall player, I do not quite understand his preference towards Goretzka. Nevertheless, both are quite similar regarding their skillset, hence it's understandable that Sabitzer wanted to move to a club where he gets more play time (or at least he thinks the chances are higher at ManUtd.). Another reason may be that Konrad Laimer will most likely move to Bayern next season, which means that the midfield will be even more packed, taking into account that Ryan Gravenberch also needs some play time. I wish Sabitzer only the best and I think that's there quite a good chance for ManUtd to buy him permanently - provided that Sabitzer shows some good performances of course. A realistic price would be 25-30M €.
