I remember Pep saying his time cycle at Clubs was dictated by other factors.
The obvious one, being the high intensity game he wanted, was quite demanding on players.
I also think Pep could potentially be mentally draining on players. I do think Pep can be prone to dark moods. Anyone who has lived with someone with mood swings, will know it can be quite draining on you mentally.
I have had the feeling all week, that there is something going on with him.
When Pep is happy, the team plays happy. When Pep is dark and moody, the performances reflect this.
Hopefully happy Pep back for Chelsea.
