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.
Chelsea strengthened very well, there was a lack of a forward in the attacking line who would effectively complete the attacks, I think that Lukaku will cope with this task perfectly! Manchester City disappointed a little, it is clear that this is only the first match, but this season Chelsea can become a very serious contender for City in the fight for the championship, so losing points is not good.
