Definitively more on Unai, god damn that was piss poor - but it was Balde's mistake that got them the chance. But Balde made many more mistakes also. But it was one of those freak matches, Japan got 2 half-chances and scored 2 goals and then did some heroic defending. When a team parks the buss like that Balde is kind of useless, but whole of Spain was useless after Japan's second goal.
The offensive output was minimal, every pass was backward.
He should risk more, and try to beat defender, because defender is always 5 meters lacking, and if he can pass him, we have a great opportunity for counter-attack.
He tried to play through and dribble past multiple Madrid players a fair few times. Entire team stopped attacking at a certain point so don't think that purely on him
He had a couple nice attacking moments near the beginning of the game, but want to see more. Also had a pretty bad defensive read in the 37th minute of the game. Otherwise was solid defensively.
