I do not fully agree with some explanations, first Real Sociedad played roughly because they were afraid of Real Madrid, so their poor challenge bagged them 4 yellow cards, none of them was excluded, the goalkeeper, the defender, the midfielder, and the winger all received a Yellow card in that match and if not for Remiro's efforts for his countless saves, Real Sociedad would have conceded at least 2 goals yesterday.
I'm not so happy with the gap Barcelona has given Real Madrid, if they flip through, it might become a problem to overcome, they have lost a game out of their last 5 matches that could have helped them as a catalyst to get to Barcelona and now another mistake from Ancelotti for thinking their last formation against Atletico Madrid will work against Sociedad but ended up as a draw, they need to do better.
