We should not use Arsenal's past mistake of missing out on winning the Premier League trophy last season to judge them that they will not win the Premier League trophy this season, even though there is a chance of Arsenal winning it. Arsenal is consistent this season, and they are two points behind Liverpool. Arsenal has what it takes to win the Premier League trophy this season.
This season Liverpool, City and Arsenal have a very small difference in points and this will be a competition between 3 teams to win the EPL title. This is not like the previous season where only Arsenal and City competed at the end of the season. This season is more competitive and I think Arsenal must be really consistent if they want to aim for the title. Liverpool and City are playing very well so far. I think the Liverpool vs City match will be an opportunity for Arsenal to overtake second place in the standings. But Arsenal also have 1 match against City in the following week. I think the title this season is just between Liverpool and City.
