I think there’s definitely an argument in regards to players who have potential being brought in only when there’s almost no alternative. Arteta doesn’t trust these players and often overplays those who probably deserve to be dropped (Willian was big example of that)

But I often think also that when we question why Arteta doesn’t rate players and they end up being moved on. I think it’s hard to think of players that have drastically proved him wrong….Biereth could be that player but again I’d need to see more than a cluster of goals in a bullshit league like the French one.

Tierney? I think the fact he’s still with us is down to his lack of fitness rather than lack of ability but football can be cruel and at 28 him going back to Celtic suggests he like Wilshere was never able to reach his full potential anyway.
