With all these transformation of the club, if they don't win the Premier League or the Champions League, it will look like nothing really transform because the trophy is what really matter the most. If the win the Premier League this season, Arsenal will be respected because they are going to send a message across Europe and they will be fear just like the way other teams are feared most especially when they see that a team is able to maintain top 4.
Fingers cross if they are going to win these season but even if they are able to win few next matches, I'm anticipating for what they are going to play if they visit Etihad. Liverpool had their own with derby and it ended as draw, I hope Arsenal can do the same because Manchester team are elated and been at home is an advantage. If Arsenal should lose the match, it will reduce their confidence in these League journey.
To be able to win the Premier League or Champions League is not an easy thing and from what Arsenal has done in the last few seasons it has been quite good, there have been lots of positive team changes that have made this team much stronger, I think that is enough and for the results it will come by itself.
Arsenal's problem since last season has been the lack of a strong mentality at crucial times and this has happened again this season so Arsenal have to prove it.
However, I also still doubt them this season, because Arsenal's team is filled with young players so when they are under pressure they will not be able to produce their best performance, as happened last season, it is likely to happen again this season.
