Liverpool, Arsenal and Aston Villa had big success in their matches. Both clubs improved their standings in the table.
A huge setback for Manchester City, which dropped from being number one to third. Fortunately for Manchester City, Chelsea is presently not quite as risky as before. Chelsea is rebuilding trying to get outstanding and experienced players. Credit goes to Chelsea, particularly for its wonderful defense, it was the reason they endured the determined assaults of Manchester City.
The failure of Tottenham to win or in any case, a draw is the most disappointing. Manchester United which has performed great in its previous matches has hope to return to the Champions League.
I don't see any significant decline in the Manchester City team this season and their failure to win the match against Chelsea is not a measure of their failure.
Chelsea is also one of the top teams in the Premier League, so the match against Manchester City is a prestigious match between two top teams, despite Chelsea's performance which has declined greatly this season.
Overall, Manchester City's performance is not much different this season compared to last season and what is happening in the current standings is normal because competition is quite fierce in the Premier League and this has been happening for a long time.
For Liverpool, it is quite an improvement compared to last season, but that is not surprising because their rightful place is in the competition for the title.
