Santiago Solari is bemused as to how Real Madrid were not awarded a "textbook" penalty after Vinicius Jr appeared to be brought down in the area during Sunday's 2-0 defeat to Real Sociedad.
Madrid were looking to move level with Sevilla on 33 points after their draw with Atletico Madrid earlier in the day, but from the early stages they were off the pace.
Willian Jose got La Real off to a great start, scoring a penalty in the third minute after Casemiro clumsily felled Mikel Merino in the box.
After the break, Lucas Vazquez was dismissed for a second booking and then Vinicius seemed to be denied a clear penalty, the Brazilian going to ground after seeming to beat the sprawling Geronimo Rulli to the ball.
