I also think the 6 teams you mentioned will be in the top 6 of this year's table. It is certain that Arsenal, Liverpool and Manchester City will be in the top four of the points table. These three groups are very strong. On the other hand, Aston Villa team is in great form. This team is now at the third place in the points table. If this performance continues, Aston Villa are likely to qualify for the Champions League. Manchester United are now sixth in the points table. However, the performance of this team is very erratic. So Newcastle have a good chance of finishing sixth or fifth in the table.
Not really sure about Arsenal, because they fail too often at the last moment. But indeed, if only considering to finish as the top four then yes, of course Arsenal still have a chance to finish in the top four but to finish as a trophy winner, I'm not entirely sure. After all, from last season Arsenal were also quite projected to be title winners but in fact, Arsenal still failed despite the fact that last season Arsenal had a better chance than this moment.
Because yes, at this moment at least there are still Tottenham and also Aston Villa who were very impressive at the start of the season for Tottenham, while Aston Villa is still in its best trend at this moment. Therefore, the competition this season is certainly more difficult than last season and yes, with a very tight competition like this then I will doubt Arsenal to become title winners.
I can't count on Arsenal in the title race either. Arsenal too often lose their consistency when there is a lot of pressure, it happened last season and will probably happen again this season. Arsenal are a team that is currently developing, but because of the team's poor mentality in the title race, they still failed to achieve it.
Liverpool and Manchester City are reliable in my opinion. Both of them are favorites although Arsenal can also be favored basically. My top favorite this season remains Manchester City, while Liverpool and Arsenal are the other favorites.
