100% Pep is not mentally in a good place. Scratching his head so much he's making it bleed on the touchline, constantly spitting. Obviously his private life is in the paper's as well.
Imo:
1. true, divorce is surely a strong reason for his problems
2. but also, he is a man who was hailed as the greatest coach ever, the innovator, the genius.
And suddenly, his football is falling apart, nothing is working, the opponents have figured them out, he is breaking negative records with City and is making some weird panic-buys in January.
Imo, it is a huge mental blow: he was on top for years and now the magic is gone.
Especially when you add to the story:
1. he started at Barca with a GOAT Messi and had a cycle for 4 years
2. then he moved to CL winners Bayern and had a cycle for 3 years
3. now he is already at City for 9 seasons and things are falling apart
But, the problems regarding his future are:
1. he has never stayed in one club for so long to build "a new cycle" or the 2nd generation of players.
He always comes, builds a team, wins and leaves.
He never dealt with rebuilding and having to sell the original players from the 1st cycle, like De Bruyne, Bernardo and similar.
So, there is a question: can he rebuild a team? He has never done it till now.
So, if he stays at City = he is in problems.
2. if he leaves, where will he go?
Barca = been there
Bayern = been there
City = been there
It doesn't make sense to go to any other EPL team.
Seria A teams are not rich, he can't win CLs there, so the only other options are Psg and Real.
Real is not an option due to his Barca's ties.
So, when you sum it all, in terms of domination and CL titles, deep down he knows that he is stuck with City.
Yet his football has bern figured out in EPL and his team is old and needs a fresh blood and rebuilding, which he has never done in his career.
So, in terms of domination and CL trophies, his future seems quite questionable.
And that is surely eating him alive.
He is not used to being mediocre.
