Think Arteta made a demand and that was that.
Emery, Sevilla work is good but PSG work is not good as they won the league after Monaco sold all their players including one to PSG. No different from Brendan Rodgers.
But listening to what the experts say, he should be a good appointment. used to working in this new arsenal structure. has tactics and plays high intensity. so we only need to sign 11 new players. actually we can keep welz as he runs around a lot too.
Anyway he is experienced so it should be interesting to see how things develop. Overall not a bad appointment. although give it 2 months til Ozim starts complaining and begging for Wenger to come back
