Nice to see Arsenal win the Community Shield. Last season he also challenged for the EPL title with Man City. I hope this season Arsenal can win the Premier League. I also see Man City as if it was a big mistake to let Gundogan go to Barcelona, even though he is one of the players who often makes the difference between Haaland, Foden and Silva having trouble scoring goals. Arsenal only killed off De Bruyne's move, Man City couldn't do much up front, even though there was still Silva, but not as genius as Gundo and Mahrez in opening scoring opportunities.
Gundogan wanted to try out a new challenge elsewhere, so he rejected the offer of a new contract from City, Mahrez also felt like it was time for him to leave Europe, he has achieved everything he could have dreamt of, what do you expect City to do, stand in the way of these players? Of course no, City sell players who do not want to remain in the club. If you stop players from leaving against their will, you create an uncomfortable enviroment in the club.
He wants another challenge so a move to Barcelona at least makes Gundogan happy to be there even though the Man City club can ensure they will win again but the choice of another team by Gundogan is Barcelona not Man City anymore.
Yes Pep Guardiola does not want a bad atmosphere because he does not want to let go of players if it is their intention to leave Man City never blocks so hard even with a suitable offer the player is always released.
For me Man City by losing Gundogan and Mahrez will not weaken their attack, Man City players can always create opportunities for goals.
