The problem is that they always slip towards the end of the season which ultimately makes them fail to win the title from Manchester City in the last 4 seasons. This season they must be able to show that they can do it even with a new coach.
Guardiola is a very good manager at playing during struggling moments, the way he messaged tho win the title last season with tons of injured and fatigued players is very impressive. Arsenal and Liverpool feel tho their face in the race, they're always very good in showing high optimism at initial moments, and their force decreases down the season.
Premier league of this season is very pregnant, I hope it delivered good, entertaining and impressive results for these teams, personally I'll be very happy if Arsenal lights the trophy for the first time in a very long time, I'm not a fan of the club, but I want some rewards for Arterta's hard works in the team.
