I agree with you. Real Madrid will really be superior in La Liga next season. That's because they managed to get Mbappe and they still have the same squad as this season's squad. Even though Kroos has decided to retire, I think Real Madrid still has other players who can replace him. Young players like Arda Guler could also be an option because he has trained with Kroos. Barcelona is in a financial crisis and no other team is at the same level as Real Madrid. I think we will see La Liga like the Farmers' League for Real Madrid next season.
La Liga will not be a Farmer's League next season because the competition will definitely still be fierce even though Real Madrid's potential to become champions again in La Liga is very wide open and the possibility could be real. However, it should be noted that La Liga will still have fierce matches and will not be a Farmer's League as you mentioned. I also admit that Barcelona is facing a crisis and Real Madrid is in better condition, but for the matches next season it will always be difficult to predict because anything can still happen in La Liga next season.
Several top clubs have brought in their respective target players, we don't know whether these clubs will be able to hinder Real Madrid's players from playing well at the start of the season, of course all clubs know the strength of Real Madrid next season with the many star players that Real Madrid has. , making defense vigilance increasingly strengthened with several clubs also bringing in compatible defenders.
Even though no one will know in the future in LaLiga whether Real Madrid will dominate the League or Real Madrid will have difficulty with so many star players, the crisis facing Barcelona will continue and make it difficult for them to get out of this crisis.
