Real Madrid didn't play well again, but they won 2-1. Real's three goals were disallowed due to offside. Mbappé was caught offside twice, and Arda was caught offside once.
Real's biggest problem was the second goal. Vini took the ball from midfield, had players on both sides in open positions, but instead of passing, he dribbled past his opponent and shot on goal. It might not have been a problem because the goal was a goal, but I think this is the team's biggest problem.
Carreras cleared the ball off the goal line in the final minutes. If this had been a goal, the match would have ended 2-2 and Real would have dropped a point, but Carreras saved the ball. Real continued on their path without dropping a point.
