Despite having players who can affect the score, Ancelotti leaves these players on the bench and does not use them. Real Madrid is a big club and has good players, but they should know how to use the substitutes more when they are playing against a strong opponent.
I think Barcelona will win again because I think they have a better game plan.
Ancelotti has been minus several players since the beginning of the season, so their plans are somewhat broken. Ancelotti's current condition does not fully believe in young players so stars such as Endrick and Guller have not had many minutes to play. Even bad news is rumored to be sold or loaned.
I understand this condition, but some League games I saw Endrick and Guller start to get playing time. Indeed, it does not seem that Acelotti is worried but it can already make the mainstay players rest. Indeed, Real Madrid always struggles with Barcelona's total footboll style, Barcelona players are able to attract 2-3 players when carrying the ball and this is not owned by Madrid. The Copa Del Rey final may be a lot of people who support Barcelona to win. But it seems that there are always surprises in the final game. IMO
