Yes I totally agree with you, it's either the coach hasn't identified the main issue or he is admitting to suggestions that he doesn't really has full control of the dressing room and I guess you understand what this means for any coach. I expected Manchester city to have improved from what we saw last season but it seems as if the teams is still being haunted by their past which is not good at all because if they continue this way it would affect their performance in the UCL
But seriously, it's not a dressing room problem because I don't really see any big player in that team anymore that can detect for Pep. I personally think that they are not big name players anymore in that City team. Manchester City is a team built on expensive quality players. Look at the team right now, how many quality do they have now as against few years ago, the big names have either left or retired and Pep didn't replace them with their own kind. I think that's the major problem with the club.
There is a point in your idea Manchester city only have few big names the club now it would be those players has no replacement the pillar of that club was the Belgian player Kevin de bruyne no player was able to replace him or should i say Pep had not seen such a talent to buy, it will difficult for Erling Haaland to score for the club because the engine room is no more with the club.
Manchester city Pep made good use of his opportunity when Manchester city was at their peak he has won the premier league if not 4 times in a row he might be leaving the club soon if there is no improvement with the club.
