If they had not won the league match after losing against both Barcelona and Milan, very bad days might have begun for Real Madrid. The team needed this win badly. Since they won by scoring 4 goals, it was much more impressive than a normal victory, it was a match that would make them forget the bad days.
They also gave a good message to their rivals that they are still very strong

I expected such score line because Madrid lost their last two games which include El Classico and their match against AC Milan in the Champions league which has cause a lot of talks by the opposition teams like Barcelona, and Madrid fans were not happy with the defeat, that’s why I expected a huge scoreline since the team will wants to bounce back strong in order to keep fighting for the Laliga. So far, there are six points between Madrid and Barcelona, Madrid need to start like 15 winning streak in other overtake Barcelona and even with that, I am still expecting Barcelona to win the Laliga because Hensi Flick is a good coach that can that is capable of winning the Laliga this season.
