Arteta is one of the finest coaches in the EPL but as a result of him not winning a major trophy like the premiership or champions league yet after having spent such number of years in Arsenal with the quality of players in hia disposal he gets so badly underrated among other top coaches in Europe. So true, Arteta did made a horrible decision not signing a proper 9 last season in the January transfer and that was a price he paid both in the EPL and UCL, that's he has to sign Gyokeres now.
As much as I dislike the club, I still have a soft spot for them but that's by the way. The problem of this Arsenal side has always been squad depth for the past two seasons and you shouldn't be faulting the manager for not getting a striker. The management should be faulted but then, they have done quite well during this transfer window, all I want to see from Arsenal is wrapping that deal for Eberechi Eze from Crystal Palace.
