Manchester City have been performing exceptionally well as they managed to win two titles last season. The team managed to win another title early in the season which boosted the confidence of every player in the team. Hopefully they can do something great in this season's Premier League as well.
Manchester City won three titles last season, and not two, they are the treble winners (CL, Fa Cup and EPL) and they have added the Uefa Super Cup to the list of their titles this season. City are definitely the team to beat and i'm pretty sure teams in England and Europe will want to stop them at all cost, City remain the favorites to defend all the trophies they won last season, so we'll see how things pan out.
I cannot imagine how would the home fans of Chelsea be thinking if their team are not able to beat Luton Town today after the club had spent so much money in the transfer market and brought in so many talented players.
This is the sort of pressure that Chelsea and Pochettino will be under this season, the club has spent so much, thus the fans are going to expect so much from the manager and players, Chelsea have to get the 3 points tonight.
