If for example Pep Guardiola returns to Barcelona, I personally believe Pep Guardiola will be able to restore Barcelona's performance. But yes, if for example Pep Guardiola still fails to restore Barcelona, then this will be proof that Pep Guardiola can only succeed at a club that has good finances . Therefore, it seems like it would be interesting if, for example, Pep Guardiola dared to return to Barcelona because yes, if Pep Guardiola managed to restore Barcelona with financial chaos like this, then Pep Guardiola would be the greatest coach of course . Because yes, basically Barcelona still has a squad that can be said to be good and therefore, if for example Pep Guardiola returns to Barcelona, I personally still believe Pep Guardiola will still be successful.
Why we must feel doubtful with Pep Guardiola? He already proved everything, he won all the prestigious trophies.
If he returned to Barcelona, he must have the chance to make Barcelona strong again. However, it is impossible to do if Barcelona management has no money. It is the same as Xavi, he has good ability as a manager but he can't do much to improve Barcelona because Barcelona management has no enough money.
