The challenge this season is going to be between Chelsea and Manchester United: they are the best two teams of the league, the most well equipped to win the English Premier League. If I would have to bet today i would pick Chelsea as I do not think they will be able to win the Champions League again. But as for the EPL, they are certainly the best. They were good last year and now they are even better.
At the start of the first season Manchester City lost there would have been more doubts about it, but I don't think so, this is only the beginning and Pep is able to overcome to become the best team in the EPL again and will certainly be a great team going forward.
For Chelsea it is possible that 2 trophies can be achieved again after many talented players have come to him, including Lukaku, because it is very influential on the front lines and this makes it possible for Chelsea to be a candidate for champions this season.
The second choice will be the most favorite team.
