Deserves credit for transforming a side that finished 8th into consecutive 2nd place finishes with good point hauls and free flowing football. However, they are now failing to capitalize on City finally being out of the running. This is partly down to them not addressing the key gaps in the team, but also Arteta failing to find the solutions and getting the team to go again. And in their best period they have totally failed to make any decent cup runs at all.
So yeah, the shine is starting to wear off. Whether someone is overrated or underrated is always a bit tricky, but his results should start to be questioned if they slide backwards this year and are once again dumped out of all the cups.
