Chelsea and Arsenal will be the challengers for the second position because so far to catch Liverpool at the top of the standings is very difficult and if we talk about the title competition for Chelsea then I think it is beyond their ability at this time. Arsenal have always failed to dominate the league even though in the last few seasons their performance has been much more promising but if we talk about the title competition their ability is not so promising and always fails.
In my opinion, Chelsea and Arsenal have a chance to compete for the title, they cannot only battle for second place. They are yet to complete the first half of the season, and Liverpool is seven points ahead of them. Of course, Liverpool's performance shows they can hold the top spot until the end of the season, Liverpool's situation is good. But their performance was very different from their last result against Newcastle, perhaps because Newcastle is always strong at home.
However, everyone no longer trusts Arsenal after seeing how they failed the previous two seasons. Arsenal started the season strong, dominating the league and defeating every club, but they were unable to win the Premier League. If Arsenal hadn't failed the previous season, their performance would have been more confident than any other side in the Premier League; but, with Odegaard's recovery, I feel Arsenal can defeat any club in the Premier League. On the other side, Maresca says that they are not prepared for the title challenge this season and are only fighting to place among the top four. However, I'm sure they're also competing for the Premier League title.
