The red card Camavinga received seems to really bother Real Madrid. Because Camavinga was one of the good players in the midfield and his absence will be felt a lot. Real Madrid is one of the few teams in the world that can turn around this score. Therefore, they still have a small chance, but to be honest, Arsenal will want to protect the victory and the score advantage by doing Park the Bus. In my opinion, we can say that Barcelona and Arsenal are 90% advanced to the next round. Also, Paris Saint-Germain did not score two goals, they scored another goal in the last minutes and won by three goals. Therefore, their job is easier in England. Only Inter achieved a slightly risky match result, but they also have the home field advantage.
Even without the red card, Camavinga would have missed the return match against Arsenal, because he received a yellow card earlier in this match, but in any case, there is no excuse for his actions, he is an experienced player but succumbed to the influence of emotions. As for Barcelona, I would say that their chances are even higher, because such a Dortmund is not capable of making up a difference of 4 goals. As for Real, there are chances, but they are very low, their defense is not ideal, and Arsenal's attack is now strong enough to score more.
Real Madrid is one of the few teams in the world that can turn around this score. The match in England was magnificent for Arsenal. Scoring three goals and not conceding any against Real Madrid on their home turf is a huge advantage. In fact, we can say that Arsenal made it to the next round in the first match. They almost passed, but they still have to be very careful in Spain. A goal they can score will bring them great comfort. Real Madrid must be very organized both in defense and offense. Otherwise, they will say goodbye to the Champions League.
