Arsenal want to perform well above their last year's performance this year. The expectations of Arteta's students are to finish the Premier League as champions. I hope they can do it but they have to beat a tough team like Manchester City. They should continue the good performance from last year until the end of the year. If they play against Barcelona, I have no doubt that the match will be of good quality. Both teams are very good.
in the next season when it starts in the premier league there will be tough competition because it is not only a problem for Arsenal who want to compete with Man City but also other teams in the premier league who are also improving their performance. My prediction is that in the summer Arsenal can finish by shifting Man City position but the chances are only small or if Arsenal can be consistent.
last season failure was because Arsenal were not consistent with their performance.
btw, the friendly match between Arsenal vs Barcelona is difficult to predict, even in other threads that discuss friendly matches, many lose because sometimes it looks like Barcelona will win, but Arsenal will win. but I predict Barcelona to win.
