Real Madrid now has a new coach and to be honest it will be difficult for them to become strong since his still new in the club so for now I'm not too sure that real Madrid will become inform or strong enough to defeat Barcelona, but I still can't also be sure that real Madrid won't pick form next season and defeat Barcelona, real Madrid has very good player and this players are ready to go far in football for example kylian mbappe, vinícius junior, Jude Bellingham, all what this new coach has to do is make them work or play as a team, if he can achieve this then I'm sure real Madrid will do more better and will be able to play with Barcelona and defeat them, last season real Madrid was unable to defeat Barcelona in all the matched they played, Barcelona was really very strong last season and I hope they continue with this form or a more stronger form next season.
For the fact that real Madrid didn't win any trophy last season those not mean they had a very bad season, they tried both in la Liga and champions League competition and I believe next season they will win one trophy.
You have to look at Xabi history at Leverkusen, since he first joined he has shown a real breakthrough, raising Leverkusen status from an average team to a team that is on par with its competitors, indeed the competition in the Bundesliga is not as competitive as La Liga but there is Bayern Munich, a favorite team in European competition.
Approximately 3 years he was able to bring Leverkusen to the top caste, now Xabi is handling Madrid, will the same thing happen? with much better support and also a composition of players with better quality Xabi will go far to meet the expectations of El Real fans for next season.
