I'd say if any big club stops with an offer for Mourinho he should leave Roma. Because Mourinho's future in Roma is not good. Roma management does not spend a lot of money to build their squad. And so Mourinho cannot build a squad with the players of his choice. Mourinho will not leave Roma if the Roma management provides enough funds to Mourinho. But if any big club wants to give Mourinho the responsibility of their team. Then surely they will prepare big funds for Mourinho to add the players that Mourinho needs to the squad. Mourinho will have the opportunity to build the squad as he wants.
Good things are built over time, look at my beloved Atalanta, until a few years ago they were in the lower part of the standings and if we go back they went up and down from Serie B
Now he's in the top tier and participates in the European cups
this is how it is done
in this way team become strong like rock
