Manchester City has won the Premier League four times in a row, I don’t think any club in Premier League history has done that. Pep Guardiola will be looking to create history with Manchester City as the club to win the Premier League five times in a row. I believe that’s the reason why they are focusing all their attention on the Premier League games and not the other tournaments. Which is why I agree with you that Manchester City were not interested in the Carabao Cup hence their performance against Tottenham Hotspur.
That is a very extraordinary achievement made by Pep Guardiola with Man City so that they can continue to maintain a positive trend in four consecutive seasons. This season there is a slight change where they performed less optimally in some of the previous matches so that it will be a little more difficult for him to defend the trophy. Pep Guardiola has created history for Man City and that is difficult to achieve by any coach before who handled Man City.
Now Liverpool is much more optimal and might be a strong challenger for Man City this season. The arrival of the new coach has made Liverpool's strength more solid so that they have managed to occupy the first position in the standings so far.
