Real Madrid had the opportunity to score more than one goal but they weren't luck enough, because many chances was wasted. Real Sociedad tried their best but when playing with a club stronger than you, your best wouldn't be good enough to defeat your opponents. Endrick only goal was able to make the difference between both sides.
Vinicius often got the chance but for some reason the player was not like last season and several failed to score. If every chance Vinic had could be utilized well, at least Madrid could have at least 3 scores. But I also have to admit Alejandro Remiro as Real Sociedad's goalkeeper was able to block every shot given by Madrid. Real Sociedad is very lucky to have a goalkeeper who is quite reflective and always ready even though he was under pressure several times but only managed to concede 1 score.
This is Vini's weakness that Ancelotti must fix, Vini is often selfish and often does not take advantage of opportunities effectively even though if not like that, maybe Real Madrid could win by more than one goal. Vini was indeed given the freedom by Ancelotti to outwit the opponent but sometimes the freedom given by the coach did not produce good results, so I think he needs to be reprimanded.
However, there was something interesting about Vini in the match because he was the first time captain and he wore the captain's armband well. He was responsible and could defend his teammates. Then his emotions were also stable and he could also reduce excessive protests to the referee.
Endrick in this match became a hero, at the age of 18 he has now scored 6 goals for Real Madrid in his first season in Europe and Endrick has now also scored goals in three different competitions, namely the UCL League, LaLiga, and Copa del Rey. Of course his prospects at Real Madrid are very bright because even though his playing minutes are minimal, he was able to score 6 goals. That's extraordinary.
