This one single champions league title is worth a lot because for the first time, Manchester City in their history won this title and this is a lot for this team I'm sure the name Guardiola will be historic in Manchester City for this title he won.
It is even possible for him to win the title for a second time in the near future.
Pep Guardiola will continue to strive for a second title in the Champions League next season, because as long as he is still able to train and improve the Manchester City team, Guardiola will continue to do his best for Manchester City. Next season, Manchester City is still very much considered as a candidate in the race for the Premier League title and also the title in the Champions League, although there are many other teams that have made changes to their line-up of players.
No matter how much players City loses in this transfer window, it will never show that they are missing a particular player, the citizens have a team that doesn't depend on a player to make the squad stronger, they have the best team in the EPL and to compete for next season title is just their target. Pep can never go without lifting a trophy in a season.
In as much as the top six in the EPL have made different changes of their first 11, I don't see them going ahead of City and I feel the Manchester City team would act more deadly next season, they'd be hard to break next season.
