It won't be very good for Real Madrid if they become out of the Copa del Rey as well. Because they have already lost most of their chance to win the La Liga title. If they get eliminated by Barcelona in the Copa del Rey as well they will have only the Champions League left. Finishing the season without a title would be really bad for Real Madrid.
Barcelona can really push them out of the Copa del Rey by the way. Because they already beat them in the Santiago Bernabeu in the first leg. I think they would finish the incomplete job.
It looks like Barcelona will be able to play even better in the second leg of the semi-finals in the Copa Del Rey. even so Barcelona only beat Real Madrid by a narrow score in the first leg, namely 1-0. so that in the second leg later Real Madrid still have a wide enough chance if they can be more productive in scoring goals. but the problem is Barcelona's defense I think is very solid at the moment. so that for Barcelona even a draw was enough to qualify for the final. and maybe Barcelona will actually score more goals in the second leg later because Barcelona will certainly have higher motivation because they are playing at home.
I just heard injuries news about Barcelona's upcoming Copa del Rey match against Real Madrid in April. There are some concerns about the fitness of two key players, Pedri and Ousmane Dembele. It's really sad to hear about Dembele, who is undoubtedly one of the best players in his position, but his body keeps betraying him. However, there's plenty of time for the players to recover and get match-fit. Barcelona has a great track record against Real Madrid, so they might not be too worried, but I'm sure Madrid will do whatever it takes to win this match. It's definitely not going to be an easy match, but I have faith in Xavi and the rest of the Barcelona team. And with home advantage on their side, they have a great chance of coming out on top. Let's wait and see what happens!
Barcelona does not have any pressure right now. At least they do not have the pressure of La Liga. So it is very expected that they are going to try to use the most force that they have in the Copa del Rey match against Real Madrid. And I believe Real Madrid also understands that very well.
The biggest thing is that Barcelona will go into this match already having a big advantage of one goal. If this was any other match I would have said that this goal advantage is not going to be good enough. But since this is Barcelona versus Real Madrid, I think it is going to be a good advantage for Barcelona.
