All teams have played 7 matches and there are still 31 games left also the point difference is very tight so all teams still have a chance, including Man United
Arsenal for example when they started the season really badly and are slowly starting to play well, when we talk about favourites I think I'm more interested in Chelsea and Man united as 2nd place.
Right now we can't predict which team will win the title. The competition in the Premier League is the most compared to other leagues. However, after 7 matches, looking at the points table, it is seen that Arsenal is far behind. They can't even be in the top 5 of the table. It is hard to predict that how Tottenham will perform in upcomming match. But I am optimistic about this team. I think they can be in the top 5 teams. Although Manchester United seem strong, their performance is not yet stable. The most stable team is Chelsea.
