Arsenal use to be a great team under Arsene Wenger. I was more familiar with the word unbeaten run from Arsenal’s legacy that year under Arsene Wenger. It has been a while though, but I am expecting a bigger performance from arsenal from then till now but still to no avail. They have shown a great improvement recently but they are still not winning any trophies yet. They are a team with that fighting mentality but they lose that mentality in the end and always give the title to their opponents. They have another chance for the next season and if they fail again, it will be the third time in a row, so they better try to win at all cost because many are depending on them to come back to those glory days once again.
Arsenal spend a lot of money on transfers and they are progressing well, but you are right in saying that they are left without a trophy, and this is the main indicator of a team's success. I understand that Arteta has done a lot for Arsenal, he was given a chance and he took advantage of it, but if this continues, then Arsenal will be forced to change something, if Arteta is a coach who cannot win a single title, then he will not be able to stay for long in the coach's place. Manchester United have a different situation, they have trophies but they play worse, so they need balance in everything.
