La Liga is definitely loosing a little bit of its glamour without Ronaldo and Messi. Barca is in big financial problems and they will have to turn to their youth players a bit more rather then buy everything on the market for the next couple of years. I actually think this is the best thing that could have happened to Barca. They were always the good when they had a couple of their own, home grown, players in the team.
Barcelona are examples for big clubs and also medium clubs that want to join top clubs. After a few successful seasons, if medium clubs over spend budget for transfer and salary, and if results in a few seasons are not as good as their plans consider, they will be in financial troubles. Many clubs got troubles and went bankrupted like Leeds United, Deportivo La Coruna, Parma, etc.
Barcelona gave opportunities for home grown players in last two seasons. Perhaps they knew that it would be fine for preparation after the era of Messi. Pedri, Fati are two of biggest young stars they have now.
