It’s challenging to predict which teams will make it to the final, including Real Madrid. so, all the teams need to be at their best in terms of performance, working hard to overcome their respective challenges in their leagues.
Moreover this. Real Madrid will face against Man City in the Quarter Final round. This even seems like the final is too early. So, it will be difficult for both of them to do their best. The only way is to defeat his opponent. And whichever team manages to win the match, that will take them to a more difficult match in the future, even though it shouldn't be this difficult, to become champions. Real Madrid must do their best effort if willing to continue to the SF. But, surely and honestly, this is not easy at al to do it.
I think the financial crisis is over. Their expenses are down and their income is very good. They don't have to sell their young stars like Yamal, Pedri, Gavi. The La Liga title this season is very difficult, but they can go further in the Champions League. Next season, with a few reinforcements, they will be a team that will be a candidate for all the trophies again. Building the team on these youngsters is the most logical move, both financially and the basis for success is that the players play together for a long time and memorize their every move. Barca have always won their greatest successes with squads based on La Masia.
It doesn't seem like that. The financial problems in Barcelona are very complex and are still in that condition. Barcelona is still experiencing a financial crisis so far, it is not an easy thing for Barcelona and also other clubs to recover quickly and easily from a financial crisis like that, which is very difficult to get out from this situation. In fact, Javier Tebas also stated the possibility of Barcelona selling their high-level players as a way to overcome the ongoing financial crisis. So far they want to do it, because it's still not finished.
