I think things have improved. We played full game of 90 minutes yesterday not looking gassed(imo improvements conditionally started under Koeman). We did not pass ball aimlessly. Actually were attacking Inter goal even when they were defending with whole team. No aimless passing from left side to right side trying to find a gap.
Building team takes time. Hate to do the obvious and point to Arteta like others have done so.
Did we really play 90 minutes?
We fell of a cliff in 2nd half for 2nd game this week, it was only when Inter sit back we were able to attack them.
Even Xavi himself admit we were far worse in 2nd half
Oh, and same thing happened against Bayern too, we were far superior in 1st half than 2nd one.
Building teams takes time, but it takes more time if you don't have the right people and give them time. It becomes a wasted time.
How many years did Arsenal waste with Continuing with Wenger? With Emry?
Liverpool did it too, Manu with Solskaer and list goes on.
Xavi himself requested the likes of Lewandowski because he wants to win now, and should be judged by such.
