Even though some key players were leaving from the club like gundogan and mahrez or even walker. The club has recruited new talented players who are as skilled as the departing veterans. I see no problem when people are talking about which club that potentially win UCL.
The transfer season has been making the situation in the club become dynamic and that's unpredictable. There will be so many changes for the upcoming seasons, especially for manchester city.
Some of Manchester City's main players have left, but there are other rumours that Walker and Bernardo Silva will also leave Manchester City, what if they really do leave? It will certainly change the scheme of their game, but I know the anticipation of a coach Pep Guardiola who will continue to maintain the performance of his team, but still if some of the main players of Manchester City leave then this will be a little decline although what I say is not necessarily, but my prediction about the Champions League is still difficult to be ready for the strongest candidate.
While the transfer window is still open anyone can offer the players they want including Manchester City players.
