Real Madrid are in serious jeopardy right now, with the Whites having the potential to end the season without a title. If you see opportunities in La Liga, Madrid have lost a lot of points and it is very difficult to catch up with Barcelona, who are leading by seven points. The Copa Del Rey should have been another priority that should have been a focus point, but the defeat in the first leg was certainly very stifling especially when it happened at the Santiago Bernabeu. Indeed, Madrid's opportunities are still open in the 2nd leg, but of course if you remember last night's results it became a very difficult mission for Madrid to turn things around.
Your worry is too much friend. Real Madrid still has a chance to win the title this season, the difference in points with Barcelona in La Liga can still be pursued as long as they are able to maintain their best performances and Barcelona lost points in several matches. The defeat in CDR first leg was of course very detrimental to Real Madrid because it was experienced at their own cage, Real Madrid was still able to turn things around in the second leg even though they had to fight hard at the Bernabeu. Anything can still happen as long as there are minutes to play, especially after Madrid only lost 1-0 in the first leg they will fight hard to achieve their goals.
Besides that, Real Madrid is still competing in the UCL, the victory in the first leg gave Real Madrid a big advantage when playing matches in the second leg. The opportunity is still there, the important thing is that Real Madrid must appear consistently to maintain the opportunity to win the title this season.
