Arsenal have plenty of experienced players. But I think they lack tactics. If the coach of the team uses great tactics and shows intelligence with the players then the team will play exceptionally well I believe.
It sounds non sense if this club lack of tactic. I meant arsenal will always be using the tactic that makes the players become feel so confident to perform better. Did you forget if arsenal was leading EPL for so many weeks last season? I can't agree if arsenal lack of tactic at this moment. Arteta has been also using some tactics last season. You can even watch it through stats of arsenal last season. Consistency is something that is missing from arsenal. Arteta must solve that problem as soon as possible.
You shall always watch it carefully. Did you watch arsenal last season or not? Plenty of tactics used by arsenal but arteta mostly used the tactics that is able pushing the players to give their best performance.
I can't even agree with you to call that arsenal was lack of tactic at this moment. Arsenal has plenty of rotations that can be used anytime.
