Barcelona and Real Madrid have yet to decide how they want to prepare their team for next season. Real Madrid has yet to buy a player, and Ramos, one of the most important players in their squad, has joined PSG. On the other hand, Barcelona, Aguero, and Depay have been included in the team. I don't think they have the ability to keep Messi and Griezmann on the team.
Until now Madrid have not managed to get a single new player in the transfer market, while their eternal rival, Barcelona has managed to get some new players even though on a free transfer and of course this is a puzzle how Madrid can compete to become champions next season, the loss of Ramos makes the Madrid defense quite fragile at the moment and it is reported that Varane has also decided to leave Madrid, and according to Diario AS (Spanish sports newspaper), the deal between Manchester United and Real Madrid on the transfer of Varane is nearing the end and will be finalized before the 2021/22 season begins.
With the departure of some of Madrid's core players in this year's transfer, of course Madrid need some really good new players for next season.
