Arsenal fans doesn’t have any options than to accept the second position every season because that's the best they can get. Even during Arse Wenger's reign, Arsenal was a business club so I don't see why they will be mad at Arteta who is always finishing on second positions recently.
In the past few seasons in the English Premier League, the teams in the first position of the points table have changed, but the teams in the second position of the points table have not changed. We have seen Arsenal finish second in the points table for the past few seasons. Arsenal have been competing hard with Manchester City for the last few seasons and they have finished second in the points table with a tough competition with Manchester City but this season they are not competing with Manchester City but are again competing with Liverpool. Now Liverpool are at the top of the English Premier League points table and Arsenal are second in the points table. Arsenal and Liverpool also have a considerable gap in points, so looking at the performances of the two teams and the current position of the two teams, it seems that maybe Liverpool will win the Premier League title and Arsenal will finish the season in second place again.
