Just relying on defense is not enough to make them able to get a draw or even impossible to get a victory and that they feel in this match. Like it or not they have to be satisfied with this defeat and go home empty-handed from the Santiago Bernabeu Stadium.
Their defense was good at the start, but it required a lot of concentration throughout the game. And it seems that they are not that strong to be able to continue to concentrate to be able to hold Real Madrid's draw in this match.
This victory allows Real Madrid to keep their distance from Girona who are just below them in the standings. Meanwhile Sevilla must be satisfied with 15th place in the standings.
Yeah I agree with you, when a team implements defensive play then the question is how long they can do it? while matches will run for 90+ minutes meaning there is always a chance to concede, especially in the second half when the players lose concentration due to fatigue. Apart from that we also have to remember that this is Real Madrid Madrid, a team that has the ability to disrupt the opponent's defense I mean they always have a way to score goals.
