As usual, Arsenal always start the season with very satisfying results, now Arteta is a little calmer after his team managed to win the two games played and managed to secure a position at the top of the standings. However, the positive results that Arsenal have just achieved are still a bit uncertain because based on experience in previous seasons, they always experience difficulties when the season is almost over, I hope this season Arsenal will not repeat the same phobia.
Things can change between seasons and Arsenal have changes in their player resource so there is possibility of considerable changes in their performances, results and ending in this season. In previous seasons, they have gotten good improvements with Arteta and from a club that struggled to get in top four, they became a main competitor for Premier League title last three seasons. They finished three latest seasons with a runner-up position that shows their consistency and they don't stop there with continuation of squad improvement in this summer.
I will buy benefit of the doubt and think of better ending for Arsenal in this season but clearly the season is long and Arsenal must try a lot in many more matches to lift the trophy.
Arsenal not playing well towards the end of the season has been Arsenal's major setback as to why they haven't won the Premier League title in the past 3 Premier League seasons. Arsenal have signed a lot of players this summer, and I believe they now have a good squad depth that will help them perform well towards the end of the season.
The league has gone through only two match days and you predicted it this way, I really disagree with you. I am not a fan of Arsenal but let's say they as all other big clubs in Premier League don't know where they will finish in this season. They will have to fight match by match and only can see clearer overview of their possible ending when the season comes to like last one-third its duration.
