I would sign losing COPA if we win LL. I just hope Xavi won't destroy the team vs Real and then they will crumble vs Valencia.
Seven points ahead of Madrid is a solid advantage and I don't think we will let the La Liga trophy slip off our hands. As for Copa del Rey, well ... that is El Clasico. The win can go either way. Madrid has a great chance to add another Champions League trophy and they will certainly play to double it with CDR trophy.
About your comments of Xavi will say this. I don't like his old school tactics and that endless tiki-taka system, but let's be honest. He does not have that type of players upfront as Madrid have
(Vini, Benzema, Rodrigo). He does not have a play-maker like Luca Modric. Torres, Raphinha and Fati are all useless players with high salaries. Dembele is often injured and because of lack of support, Lewandowsky is not performing as usual. We have way too many players that need to leave. La Liga is possible to win with this squad and that is because Madrid lost too many points this season. But the Champions League is not for us right now. We need a serious rebuilding in the summer.
