You seem to be making an assumption about what I stated. I don’t think Arteta had a problem with Auba from the outset but it became increasingly apparent over time that he lacked the strength of personality to deal with him when difficulties emerged. It’s hard to keep a player motivated when you’ve given him a 300k a week contract but the coach is there to do just that.
The fact remains that we don’t really know what these red lines were, being late for training and being late a day back from holiday are of course not good behaviour and need to be addressed but they need to be addressed head on, not with passive agressive standoffish petulance that Arteta has shown.
Guendouzi is no doubt a little shit and I don’t think much of the rest of the team had much love for him, but a good coach had the potential to turn that fiery attitude into potential….Arteta as is so abundantly clear cannot handle this.
As I have said and will keep saying, you will not see the last of this behaviour from Arteta it’s ingrained in him, someone will challenge him and find themselves training by themselves or he will find a scapegoat.
