I was not trying to say that Stuttgart should be buffed in general(I think their ratings are fine), I just think Nübel is too bad. He has terrible average ratings(in 2 different saves he has under 6.5 after 17 matches). He is on a 2 star level for Bayern, so he is clearly too bad in the game(even worse than Peretz). His sofascore rating last season for Monaco was 6.93, which is still decent and now he is performing really well.
And this is clearly an issue: Ulreich seems to be so bad in the game, he is playing for Bayern II. I mean he should not get a huge buff because he is 35 years old, but he should still be better that he is not getting placed in the 2nd Bayern team.
