You're absolutely right, it's only a matter of time before Barcelona competes with Real Madrid. However, the Barcelona club is now very struggling as they have been going through financial problems for a long time. A good and skilled coach needs a lot of money. According to the current situation of Barcelona, I think it is very important for Barcelona to have a maximum effort for an experienced coach. So that Barcelona can return to form next season and maintain their reputation among football lovers
Barcelona doesn't need a lot of time if they build a team with young players, especially as their rivals Real Madrid have everything to be able to compete fiercely in the title race, so I am sure that it will be almost impossible for Barcelona next season to be able to compete fiercely with Real Madrid.
A team that is in a slump like Barcelona and they are experiencing financial problems so they can't bring in star players so I don't think they will rise in the next 5 seasons, by revival I mean their return to the same level as several seasons ago.
