Real Madrid star Toni Kroos has admitted he is still angry about a refereeing decision against Sevilla that could cost his side the league title.
Los Blancos dented their LaLiga hopes earlier this month after playing to a 2-2 draw with Sevilla.
Zinedine Zidane's men were awarded a penalty in the 78th minute for a foul on Karim Benzema, but the decision was overturned after the video assistant referee spotted a handball from Eder Militao in Real's box, with a penalty then being awarded to Sevilla.
Kroos feels that if Los Blancos do not win the title on Saturday, the above decision will be a big reason why.
"Zidane never really says anything about decisions and he always protects the referees. So, the fact that he went to the referee after the game was a sign that he too felt a little ripped off, as did I.
"The referee tried to justify himself, but it's a very clear wrong decision, in my opinion. My opinion is very clear and it is very rare that I disagree with the referee at all. I did on that day.
"If you feel you're being disadvantaged, that's one thing where I say 'it's not on'.
"[Militao] had his back to the ball and didn't even see the ball, while in slow motion you can see that the ball first goes to his shoulder and then to his arm. We were told that if the ball ricochets off another part of the body, then it's not a handball.
"To look at it again and to revise it, because he didn't whistle it live, is a serious intervention in the championship.
"If, in the end, we don't have enough [to win the title], in my opinion, this was a situation that also contributed to it. For me, this is clearly a situation that had an influence. It's not about being bitter, it's about being angry."
