Even though Man City has suffered the loss of a captain who was very important in winning trophies this season, Ilkay Gundogan is a tough guy and he believes in his decision to go anyway. And I believe that Pep Guardiola will definitely try to find the right replacement. Besides that, Pep Guardiola has many player options in his squad. Ilkay Gundogan journey at Barcelona is a new chapter and he is sure to gain the trust of Xavi to lead young players who are hungry for goals. So that this match can be seen how Ilkay Gundogan role can encourage young Barcelona players to achieve their ambitions.
IMO, the system Pep has implemented this season has had a big impact on their performance. in fact, City always calms the game with a landslide score. not only because Pep is a smart coach, but teamwork and solidarity, the chemistry of the players has been very well established. that's why, this season is City's season.
Now, the captain has left and City will automatically look for a replacement. it is clear, the departure of Gundohan makes Pep Guardiola will look for an ideal replacement candidate. to bring in a potential replacement, it is not easy. because of that, City became interested in hunting Declan Rice. but what is certain, what Pep Guardiola has implemented in his system has been very effective. so he just needs to carry on, plus find an ideal Gundohan replacement. I'm pretty sure, they'll get a player worth it. in fact, it is very likely that Gundohan's departure will not change City's performance as a whole. City will still be the favorite team compared to other teams even though a new competition has not been rolled out.
As for Gundohan, I think he will quickly adapt to his new club. moreover, Gundohan has the experience and mentality requirements that can have a big impact on Barcelona.
