Arteta is seriously cooking... It's a good thing to see that Arsenal are really poised towards improving the quality of their squad for the next coming season. Zubimendi is a huge plus to the team and addition to Gyokeres when all negotiations are finalised and deal closed, then we can be confident of a different ball game from Arsenal not just challenging for the EPL trophy but in the UCL as well.
Arteta is not serious. For how many seasons now Arteta can not boast of winning any trophy, so there is a need for them to be serious because Arsenal have brought a lot of disappointment, and when they don't do the needful, I don't think anything will change. Arsenal is bigger than this, so why are they behaving the way they are We can not be too sure about how we want everything to be, but to some extent, they should win at least the Premier League, but countless opportunities and since they seem to be a little active on the transfer window lets hope that things will be better this season if not i was not impressed with last season at all because i expected more from them.
Just like you I have also at other times casted all blames on Mikel Arteta for Arsenal's seconds class performance in the EPL for the past three seasons. But then for some reasons I had to also look at the management of the club what they are also doing in their efforts to make the club seriously challenging for trophies by releasing necessary funds to get the required legs for the goal ahead. The only time I can also blame Arteta was in the January transfer where he blatantly refused to sign a top 9 for his team, which would have helped in in last season's title race against Liverpool. Perhaps, he has started seeing his mistakes and is now amending things...
