I am not saying that divorce is the main factor why Pep Guardiola is no longer great at managing the club. Because every element, both external and internal, forms Pep Guardiola today. So one of the many problems with team performance, unstable players, dependence on Rodri, loss of player confidence, and the psychological condition of the coach are the complete ingredients that give birth to poor performance. Now there is only 1 match left which makes everyone not put too much hope on them.
Pep Guardiola will work professionally despite the issue of divorce with his wife, even where the result of this divorce is because Pep Guardiola is too focused on his work as a coach so there is no time for family, I think this is wrong news because it is only read in some media.
The factor you mentioned can be a material where Manchester City's performance becomes bad, some of the main players, especially dependence, can also cause other internal problems.
With one game left there is still hope of advancing to the playoffs and it will also depend on how the other results go.
