You are been biased for these statements you made about Arsenal, I think you have to keep sentiment aside and tell the truth because everyone has seen the changes Arteta has brought into the Arsenal squad. His effort towards winning the League in the last two season were recognised because the team stood out to outperform Manchester City, just that inexperience let them done to gave Manchester City the title.
Last season, it was due to lack of prolific striker; and even though no striker has been signed yet, I don't think Arsenal will lose some kind matches they lost season because one of them has been corrected already.
Nevertheless, you cannot desipute the fact that Arsenal have good creative midfielders, they have good squad depth and have signed good players that will help the team, the only problem now is a reliable striker because Gabriel Jesus is not reliable due to injury.
I have to say that is true that Arteta is doing something incredible which is why I believe that he is doing something incredible with the team and there is nothing wrong with still saying that he has to do more.
If you are going to just finish second every year, then there is nothing worth celebrating and just because they are better, it doesn't diminish the fact that the fans are expecting him to win this.
It's clear that we are going to end up with something bad if he leaves without a league title, they barely lost twice in a row now, if they win one then it is all okay, Klopp lost so many to City the same way, but got one and got a UCL as well so all is fine with him and Liverpool celebrated him, if Arteta wins nothing then what was this whole thing about?
They could have been seventh all we care, as long as you do not finish the league with a title, then there is no reason that they could end this period in a good way, he should get a title this season if he wants fans to like him.
