The competition in the Premier League is very tight. Last season it was only Man City and Arsenal. But, this season Liverpool and Tottenham also have a pretty good chance of becoming Premier League champions. No one thought that Tottenham could play this well so far because they had lost Harry Kane who moved to Bayern Munich. Liverpool also has a pretty good performance, and when compared to Tottenham, I think Liverpool has a more promising squad.
Man City, Arsenal, Tottenham and Liverpool are the four clubs that have a better chance at the moment, the four clubs can be comfortably in the UCL zone without facing competition from the other two elite clubs Chelsea and Manchester United. I think the second half of the season the competition will be tougher than now, Chelsea and United will definitely try as much as possible to improve their performance so they can finish where they should be, namely the European Champions League zone.
The progress achieved by Tottenham has indeed impressed everyone, many previously assumed that Tottenham would experience a downturn after releasing their captain Harry Kane to Bayern Munchen. Ange Postecoglou was able to create an atmosphere and stability within his squad, even though in terms of depth Liverpool squad was better and more promising. Tottenham should be well watched by the current EPL title challengers.
