Spain is not an option because of his Catalan roots and connections. He wants to manage Brazil some day, may be he will take over from Ancelotti in 2026?! Who knows.. Return to Barcelona is possible but it will be at the end of his career and not as a head coach. Italy is def a possible destination but it will be VERY interesting wich club would he choose.. Roma after Mourinho ?! AC Milan as one if the clubs that inspired him to be a coach ( The Sacchi era)?? Napoli as the romantic choice (The club of Maradona) or of course Juventus as the traditional dominant force in Italian football.. Lazio or Inter in my opinion are not options for him..
Previously there were very strong rumors of him going to Juventus, but then he extended his City contract. I could see a remote possibility of something like that down the line.
I think a national team job makes sense eventually for if and when he wants a slower pace. Guillem Balagué recently joined in speculation that Pep would coach the English national team when his City contract runs out. He also speculated that De Zerbi would take over at City after Pep. He probably is just speculating and has no clue like the rest of us. In the England case, after he has finished making the Prem a farmer's league and most of the key England players have either been coach by him or his minions borrowing from his style it could ease the transition, since one of the difficulties with NT coaching for Pep would be implementing his style.
Pep's trajectory is interesting because the prospect of even approaching SAF is so exceptionally remote you laugh off the idea of it for most. There are a lot of details and context to this topic but, in the main, I see about 4 key areas weighted differently by different people:
1.) club level winning and dominance
2.) national team winning
3.) stylistic or tactical influence on the game and
4.) romanticism, force of personality and coaching narrative.
Pep has already made significant, historically-great headway on elements #1 and #3, even if he might not top the list in either of those categories. With these things alone, he has probably done enough to at least be in the discussion amongst the greatest the game has ever seen. He could easily still add to his case in these regards as well. One more CL win and he is tied for joint most ever. He already has the most CL semi-final appearances ever and a bunch of other records that don't need repeating.
He is also young enough that he has opportunity to add element #2 to his case as a way to distinguish himself from SAF with a bit of luck. Carlo could we be on his way to doing exactly this with Brazil. The likes of Rinus Michels, Marcello Lippi and Vicente Del Bosque and probably a few others also have club success and NT success. Michels' club success was good, but not Pep level. But he is frequently classed as the leader in element #3. Lippi is very good in all of elements 1 to 3. While no tactical slouch, he is probably classed below Pep in this regard. Del Bosque probably doesn't have enough of a claim with element #3, but had good, if brief, success in element #1 and great success in element #2, even if there is a bit of a perception that he was just along for the ride.
Pep will likely never have much romance or charm to his story for element #4 to rival other great coaches. It's just been machine-like domination pretty much from the outset. Of his prospects in the realm of possibility, taking a Juventus back to the top of Serie A and possibly even Europe could add to his case in this regard. But is that really giving anyone warm, fuzzy or inspired feelings? It's Juventus, FFS. He probably needs to have a calamitous fall and somehow manage to rise back up to the top to make any real headway here, and I don't see this as likely.
His trajectory does have some interesting pathways to add to his already-strong case though. Imagine the hype if he manages to win something with England if Southgate does not. You think the hype is bad now?
