Guendouzi has potential.
Arteta has to set his stall out, so players know what is expected, and I can’t blame him for leaving out Guendouzi.
It has happened between far better players and managers in the past.
If we can’t get what is needed, then reintegrate him into the team. We can’t let him go for nothing. If we get around £25m then sell. He has potential though, and if he is not motivated by seeing the energy around the team and fan base at the moment, with the signings we are making and being linked with, then nothing will salvage his Arsenal career.
