It's true that Pep Guardiola is a great coach and although he missed Gundogan going to Barcelona, it seems that Guardiola is also ready to regenerate the Manchester City squad. We know that Gundogan is no longer young and it is possible that next season we will see Kevin De Bruyne's turn to leave Manchester City. Everything is well understood by Guardiola to determine the composition that is suitable for Manchester City's strategy next season and maybe we will still see Manchester City will sign two or three more players this summer.
Gundogan departure for Barcelona did not bother Guardiola with the condition of Manchester City's midfield for next season, he still has several other quality midfielders to rely on, especially since Manchester City have just brought in Kovacic from Chelsea. Players in a team always come and go, Guardiola, who has a lot of experience, is not too burdened by this condition.
Manchester City, which has just won the treble winner, cannot be separated from Guardiola ingenuity in selecting players to fill out the Manchester City squad. Kevin De Bruyne has improved rapidly under Guardiola, he has been polished to become a star player who has always been a part of Manchester City main squad. Guardiola can put players in an ideal position that makes him comfortable while playing, there are so many stars that Guardiola successfully orbited during his time as a coach. He can always find suitable substitutes to fill the positions left by players who go to other clubs, besides that regeneration needs to be done to rejuvenate the squad he leads.
