I was seeing Manchester City as one of the favorite teams to win this season champions league trophy but after I watched Manchester City's performance against Brighton in the Premier League, I don't think Manchester City is ready to compete for the champions League trophy this season unless they are able to improve their performance before the champions league starts and prove me wrong.
Manchester City will still go out to win the champions League this season it doesn't matter how well they do in the EPL this season but the Champions League competition is a different game and they may go all out to improve their performance and if that is done Manchester City will be ready to face other good teams if they are lucky they can get to the finals. City has gained only 3 points in 3 matches in the English Premier League this new season they have a lot of things to improve on if they what to make it to the finals they season.
Manchester City still has plenty of time to improve their poor start to the Premier League season, having only won once and lost twice in three matches. Their next match is against Manchester United, which I don't think is an easy opponent for Manchester City.
And I'm sure Pep Guardiola will continue to work to get his team back to its best, but the loss of Kevin De Bruyne, Jack Grealish, and Kyle Walker will be a task that may take time, as it's too early to judge Manchester City solely on their poor start to the season.
The Champions League is a more important league, so I'm sure Pep Guardiola will continue to work to improve it to compete in both the Premier League and the Champions League, and we'll see.
