In current era, 3 - 0 lead is nothing but still things are going to be challenging for both sides with Real Madrid could be on his best due to this difference and want to bring themselves on level but Arsenal is also in good rhythm which give them good advantage and they are doing decent job in this event as well.
Everything is possible in football. And Real Madrid has made such a difficult task possible many times in the past years. Real Madrid is a very experienced team on the Champions League platform. Madrid will play their home match in today's match. So if Arsenal players do not play well, especially if Arsenal's defense is weak, then they have the possibility of losing by a large margin.
Arsenal's main strength is their defense. We have seen Arsenal's strong defense in the Champions League matches. Real Madrid could not break Arsenal's defense even in the first leg match. I am looking forward to seeing how Mbappe, Vini and Bellingham perform today against Arsenal's strong attack.
