Arsenal have been more inconsistent this season than Chelsea, but I wondering why no one is talking about them, but everyone's talking about Chelsea as if any one of us expected them to win the title this season.
I think the reason why Chelsea have gotten more attention from the media concerning their performances this season when compared to their city neighbors Arsenal is because they started better than Arsenal and were been considered by many as a serious contender for the English Premier League title this season.
That said, I totally understand your opinion about Arsenal and why we should also talk about their inconsistency. Arsenal who finished in the 2nd position of the league table in the last two seasons at the start of the season were expected to be one of the major contenders for the league title but surprisingly, Mikel Arteta's men have been too inconsistent. At the moment, I don't consider either of Chelsea or Arsenal as a team that's strong enough to challenge Liverpool for the league title this season so I think it's going to be an easy ride for Liverpool to win the league since reigning champions Manchester City is also having a poor campaign
IMO, Chelsea are not so busy with participating in bigger competitions like the Champions League. Although Chelsea's schedule is quite tight with participating in several competitions, even so, the teams they are playing against are not super tough teams. That's why Chelsea can focus on improving their performance in the Premier League, plus Maresca is able to handle Chelsea very well. But in any case, Chelsea's performance deserves appreciation, they are still in the top four of the Premier League table so far. In the Arsenal camp, there are several factors that make them inconsistent. For example, several players were given red cards in several matches, injured players and Odegaard's absence were very influential as team captain. Plus Arteta has changed his pattern and system several times, unfortunately it didn't work well. They also have a focus on the Champions League, the teams they play against are not easy opponents and the impact is that sometimes their performance is inconsistent when playing in the Premier League. As for Liverpool, they are quite consistent in maintaining their position at the top of the standings. Four points ahead of Arsenal and Forest, plus having one postponed match that can be used to widen the gap between the pawns and the team below them. However, the journey is still long and there is no guarantee that Liverpool can easily win the trophy this season. Let's see how the Premier League continues, perhaps in some of its matches Liverpool experienced an unfavorable situation. If they want to win the League, then they must win match after match.
