Arteta said that he is very unhappy because Arsenal did not have players in the winter transfer season. When Champions League, Premier League will continue with more important and decisive months, Arteta has reasons to feel that with unfixed problems in attacking system especially at a striker position, Arsenal will have big disadvantage and might fail to win Premier League title in this season, and it will be a third failed season for them.
Arteta hopes that in each transfer window he will receive funding for new transfers, but this does not happen, especially since Arsenal have already spent a lot of money, in my opinion they are one of the leaders in the Premier League in this indicator, but at the same time they cannot become champions, first City hindered them, now Liverpool, each time someone hinders them.)
Arteta is very excessive because since his arrival as Arsenal coach he has been given a lot by management to build this team but until now he has not given the results desired by the team, I think now Arteta must focus on developing the existing squad to create a solid performance because if you look at all sides Arsenal players are quite good in all lines, it's just a matter of how Arteta can use it.
Arsenal problem this season is that they often can't maintain the consistency of their performance and I think that is the full responsibility of a coach.
