I assume this is the incident with Schulz that is mentioned in the thread about him at Dortmund.
It's not even particularly a bad pass, he just can't control it.
I think he's 18 here. The attitude needed squashing a long time ago.
I understand frustration, and communicating to people when you want them to do something better - but a flat-out "you're shit" in the middle of a match is disrespectful and uncalled for.
Nico Shulz should have had a long hard word with him in the changing room at half time or after the game, a one that left his nose flatter to his face.
