For this season, it is better to accept whatever the result is because Manchester City has also been eliminated from the UCL and for the Premier League title it is also certain that they will not be able to compete for it, what can be done until the end of the season is just to make sure they stay in the top 4 or can go up again to get UCL ticket next season.
Competitions that are still being followed besides the Premier League are only the FA Cup and the Club World Cup so Manchester City can focus on both if they want to bring home the championship trophy, I sure next season they will be able to get back on track and can perform like the previous season.
I agree that Manchester City season is not going as well as they wanted because they got eliminated from Champions League and it is unlikely they will win Premier League title. Now it is best to accept how things are and focus on finishing in top four so they can play in the Champions League again next season. Since winning Premier League title is no longer possible Manchester City can focus on FA Cup and Club World Cup which they still have chance to win. Winning one or both of these competitions would be nice prize and would help boost team spirits. As you said next season Manchester City will probably come back stronger and play better.
Manchester City really have nothing to achieve this season.
Firstly, they are out of the Champions League and compared to the way they are performing, other teams in the Premier League are performing well, so while other teams have the potential to do well, Manchester City In fact, there is no chance of doing well in the Premier League. Now Manchester City can try and compete to the maximum to keep themselves between 1 and 4 in the points table. Basically, if Manchester City can't place themselves between number one and number four of the points table this season, then they won't be able to qualify for the Champions League next season. Maybe they can strengthen their team in the next transfer window but if they are not in the top position of Premier League with this team then next season with strong team but they have to play in Europa League.
Hopefully the team managers and players are planning on all these issues, maybe Manchester City will try to play the future matches according to that direction.
