Despite many teams have improved doesn't mean people don't know the team that will win the title, base on their starting from first, second and third match, we have see teams with highest points and goals in this premier League tournament that convinced some people to see Chelsea and Liverpool the two team that will play the final match this season, talking about Arsenal in this tournament, I don't think their new players will assist the team to repeat second position in the premier League tournament because they are lacking in the area of forward players which is the reason behind their failure in the home of Liverpool, I don't know if Arsenal will make a good turn back to win their next match to prove to people that they have put more effort to challenge any teams in the remaining matches.
We can indeed see the strength of the teams that are ready to compete this season from the early matches. But it is still too early to classify these teams based on their performance in three matches.
The Premier League competition will still go on for a long time. We might see some changes in the standings at mid-season or even close to the end of the season that could be surprising. As long as the competition at the top of the standings is quite tight, all teams will still have a chance.
