Real Madrid, whatever happens, will not qualify for the second round tonight. You can leave the classification very on track, almost sentenced, if you hit the table and beat Inter at San Siro, because it would mean leaving the Italians on the edge of the abyss, almost eliminated.
Whites currently have 4 points, the same as Shakhtar, while Borussia Moenchengladbach leads the group with 5 points. The bottom is Inter with 2, so the Italians play it tonight. Madrid is at stake, although not so much: it will continue to depend on itself even if it loses (winning the next two games it would be mathematically in the eighth).
What yes would get Real Madrid by winning to Inter is the possibility of qualifying mathematically the next day, in which he plays against Shakhtar. If the Ukrainians lose or draw against Gladbach, Madrid would be in the second round if they win. If Shakhtar win, Madrid would also be one victory away from getting the pass, although in that case, in addition to winning, they should also be able to turn the goalaverage around with the Ukrainians, who have won it right now. after 2-3 of the meeting at Di Stéfano.
However, the empate would not be a bad result either for Madrid, because he would leave the very on track group likewise if on the next day they beat Shakhtar, although in that case they would almost certainly have to wait until the last day to qualify.
