Yeah that's pretty much what I was saying. Those comments are new but the sentiment has definitely been lingering about for a while, Ricky has mentioned it before too. AMN seems to lack drive and professionalism, his complaints sounded way out there for someone who shouold be chomping at the bit to play for Arsenal, even his mistakes seemed like they were a continuation of it.
We have plenty error prone players like Leno Xhaka or Mustafi but they always seem to come because of poor judgment of a situation or technical ability, with AMN it was regularly because he completely switches off which I assume will go down worse with most coaches.
