Guardiola is not a new coach he knows how to replace players who have left Manchester City, I'm sure he will get new players to replace the missing important player positions in his team squad, although in the end there is a process of time to adapt again, but with Guardiola's choice of course I sure he will find the right players considering his next goal is again to be better than last season.
At least Manchester City didn't lose other important players and only a few could possibly be replaced with new players who have more potential and are much better, I believe Manchester City will win the league this season including the UCL, although it's a bit hard to see that there has been a change in Madrid's strength too. with the young players there. but Guardiola knows how to beat them in the UCL.

Seeing how Pep Guardiola gave great success to Man City, i truly recognize his sharpness as a coach, even now i really remember how he immediately threw away Joe Hart when he was just inaugurated by the management of Man City to become a coach.
In this new season, Man City will face other great EPL teams who have successfully carried out several major overhauls in their squad, such as Chelsea, Liverpool and Man Utd, even so, the chances for Man City to become EPL champions again are still great because no drastic changes have occurred at the club.
