I was just thinking about what it would take to see Pep Guardiola getting fired!

I have always thought that it is impossible for him to ever lose his job and I still think it is, but from a hypothetical point of view, I wonder when a club's management would decide to sack him?

Four losses is of course not enough. He could probably lose 8 consecutive games and still wouldn't get fired. Probably 12... But it is a new situation that Pep Guardiola hasn't been in yet. This could either snowball and Manchester City is far more nervous than usually or they will soon answer with an impressive winning streak.
Nothing is impossible when we talk about football, Pep was told if he wouldn't be forever at Manchester City, because Pep's contract will expire in the summer of 2025 and there are no signs yet about an extension which I think is possible he will leave Manchester City and begin to new challenge to another league. The other situations, he was told if he want take a break on football for a while and take a vacation as Jurgen Klopp did. And maybe it could happen after this session over, or at least Manchester City get trophy.
