You are right dear this season Premier League is more competitive. Manchester City used to dominate but now other teams have chance. Last season Manchester City only lost four games but this season they are losing more. Top teams like Manchester City Arsenal and Liverpool will likely lose six games each by end of season. This shows Premier League is getting tougher. Chelsea has changed a lot under Coach Pochettino. They are now a strong team unlike the past two seasons. Pochettino deserves praise for building such a good team.
I don't think the premier league has become more competitive as Manchester city dominance has reduced but I think Manchester city are in a bad form because some of their key players aren't available for them to be used and Pep Guadiola doesn't have other better options to use and this is making him to lose games that were previously easy for him to win. We have more quality managers in the premier league now but let us wait for when Manchester city are back in form as their injured players return before we can see how the league is going to be before we can make conclusions. When Manchester city are in form, I don't think any manager can defeat them.
