Regarding 3 draws in 3 consecutive matches, then I think that is one proof that Arsenal are not ready to win the Premier League title this season. Manchester City are the team most likely to win the title this season although Arsenal still lead a few points clear in the standings. If Manchester City manages to beat Arsenal at next week's meeting, then Arsenal will likely fail to win the title.
After Arsenal's draw with Southampton, I lost confidence in them. I'm sure the pressure is too much for them, but that's no justification to toy with the league title after they’ve come so far to achieve it and maintaining it for so long. Arsenal is just concerned with the Premier League, but Manchester City is vying for both the Premier League and the Champions League.
Given that Manchester city have never won the Premier League, I feel they would like to win the Champions League. Arsenal should make the most of their encounter with them in order to preserve a solid win while focusing on how to win the remaining matches before the season ends.
