The problem there being that this particular manager said Saliba wasn't ready when clearly he was, only brought in Saka due to others being unavailable and didn't rush to play Nwaneri even when Ode was injured and we desperately needed some extra quality in the attack
So I don't trust what he personally sees in training tbh
I do get that this may not be a big deal to some btw, but for me I really enjoy seeing young players come through and to see what they can do in match conditions, given last night was a dead rubber it was the only thing that held any interest for me tbh, hence my disappointment
Also I think it speaks to the bigger point about how overly cautious Arteta is, to the point where it works against him, because he overworks some players and doesn't give others any opportunity to improve, gain experience and show what they can do
