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.
Maybe you are right that Arsenal are currently under quite a lot of pressure. because the atmosphere at the end of the season must be a burden for them. They have struggled from the start at the top of the table. so it would be very sad if they finally had to give up ranking 1 to Man City. But to be honest I was a little disappointed with Arsenal with the draw they got against Southampton. because after all Southampton is the weakest team currently in the premier league which is also at the bottom of the standings.
Man city is likely to have the chance to win the title again like last season. Because Man city is truly extraordinary because they are able to maintain consistency in every competition they are currently facing.
