It is too early to write Arsenal off from the Champions League. It is not because Real Madrid played very well in the last match that they are still in the Champions League, they are just lucky in that match. Alvarez's misfortune is helping them to reach the quarter-finals of the Champions League. I would not like to sit down with pen and paper in such a big match. You definitely have to win matches like the quarter-finals on the field, if someone looks at the previous statistics and declares Real Madrid as champions, then maybe he is a blind fan of Real Madrid. They are under threat with their weak defense. Maybe Arsenal can use this weakness to knock Real Madrid out of the league.
Here I agree about these, things are surely going to be interesting because both teams are on same level of performance while both are having injuries problems which is giving them concerns now for this important match both will enter with their best sides as they have enough time for doing things.
Prediction is always about these games are not easy while many were writing Real Madrid off after their narrow win at home, but they have done good job and ended as winner even controversies are happening, but it's all about part of sport having spot into semifinal is always great even Real Madrid is great, but now changes are happening. New format bringing good excitement about many teams while few teams were not considered as best now having strong case of win which is making this event more interesting.
