Ramos is entirely responsible for Sevilla's defeat against Barcelona. How could he make such a mistake in the end? Such a mistake was never expected from a world-class defender like him. The way he scored his team's goals, it felt like he was a Sevilla player and not a Barcelona player. I don't understand how he got the ball back from the point where he was standing.
Own goals are not unusual. We have seen many players score own goals before but in a different way.
Ramos was standing slightly in front of the goal post, from where he was standing a defender would never pass the ball back because the empty goal post was right behind him but why did he pass the ball back.
He might be dropped from the team for the mistake he made.
That's a normal thing in football, especially for a defender who wants to anticipate the ball and I think you are blaming Romas too much, he didn't do the own goal well, everything that happened was by chance because he was running and no one expected it. The ball came to his feet and went into the goal.
You are exaggerating when you say that the team will leave him because of this mistake, Sevilla were just unlucky in this match even though they played quite well and it cannot be denied that both teams put in a good performance, only this time Barcelona was luckier.
