I dont think Manchester city's poor performance should have anything to do with the coaches personal life because we all know this team have been through a lot including injury worries and also the problem of ageing players in the squad who needs to be replaced and also the problem of psychology which has impacted the entire squad as a result of their poor performance from previous games where they suffered some serial defeats both in the domestic league and in the champions.
Haven mention all these it wouldn't be nice to say that Pep's personal family problems could be responsible for the team's poor performance because if the story of his wife wanting to file for divorce hadn't come out to the public then no one would have known about it or insinuate that it could be the reason why the team is suffering.
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.
