Perfect timing for him to come back was after tito found out to be sick and later sadly passed away, but he didnt want to ruin his legacy and instead he choose to coach bayern in boring bundesliga with those 3-4 hard matches in a whole season in CL, maybe he was impressed by them when they crushed barca 7:1 in CL, then he picked oil club, he lost me there, i dont miss him, if his gonna come back, good, if not, thats okay, but i will never wish his comeback even if barca plays most boring football.
Look at zidane, he will never repeat what he did with madrid in those 3 season, he took 1 year off, madrids best player left, they were never in worse shape like now, they need to do major rebuild of team, and zidane comes back to help them with that, he doesnt give a fuck about his legacy, just by that he is more madridista then pep is cule, even if zidane didnt spend such long time at madrid as a player.
Pep next destination is more likely PSG
