The season may look to have more to offer but right now we almost done with the first half of the season and any team at a top position and still but in as much effort in the next half of the season can have a very good turn out at the end of the season.
Well if I were to say who would be in the top six position at the end of the season I would say Arsenal at the first position just because I think they are solid and deserve it and then Manchester city, Liverpool and Aston villa then in six and fifth would be Newcastle and Tottenham.
I agree with you that Arsenal are more solid than Manchester city and Liverpool currently. I just don't want to totally discredit their credentials as per having won the league recently. A wounded or ill equipped champion is still a champion. Somehow I think Liverpool are more of a serious contender than Manchester city. Liverpool are going about their business slowly and silently. For me they are the bigger threat. They have the technical know how to go the entire season and continue putting together points.
The thing is that, Arsenal are controlling much part of their games this season and I'm banking on their ability to control games to put put them ahead of any team. I think if Liverpool go long into the Europa league and continue all their running, it might affect their title run. Also a lot of things can still go wrong for Arsenal and other top 4 teams but I think on the balance of play this Arsenal squad is more solid than both Manchester city Liverpool. If it comes down to Liverpool doing the chasing I think Arsenal will edge.
