But keep in mind that Pep Guardiola is an adventurous person, so there is always a possibility he will leave especially according to his statements if the club he loves calls, nothing can stop him from leaving and that club is Barcelona. Pep Guardiola will always be adventurous looking for new experiences, add insight and revive clubs that really need his services. Even though at this time Man City is comfortable with the presence of Pep Guardiola, it is likely that his departure will leave many gaps.
I don't think Pep will go back to Barcelona any times soon. He has never said he will go back to Barcelona if they come calling, in fact he has said his path doesn't lead to Barcelona any time soon. Pep will always be a Barcelona fan and he's not ashamed of saying that. He says it any opportunity he gets. Pep supports Barcelona, but that doesn't mean he wants to go back to coaching them.
I think Pep will see out his contract at Manchester City and that till 2025. That means he still has two more seasons to be at Man City. Pep himself has said when he signs a contract he likes to respect it. Add that to the fact that he has a very good and working relationship with the management of City and is already very successful in the club, he won't be leaving till the end of his contract.
Barcelona doesn't have the money for Pep Guardiola to become successful coaching the club, Pep Guardiola has been spoiled with so much money that it'll be very difficult for him to become successful with Barcelona as they're now broke.
Statements like this are funny because it make it seem like Pep is only successful at Man City because he spends money. No big club in Europe doesn't spend money.
Liverpool, Arsenal, Barcelona, PSG, Madrid, Chelsea all spend ridiculous amount of money, but none of th can boost of the success Man City has.
When Pep coached Barcelona he didn't spend half as much as Madrid but he still dominated the league and Europe. We know today's market is different, but with what Barcelona has Pep can make them a fearsome side in Europe if he was their coach.
