Real Madrid were good in the first half but I can't say the same for the other half. 
After capturing the 2-0 lead they got relieved probably. At least they maintained the same score until the end. It was Bellingham's day with a goal and an assist. Nice to see Mbappe scoring too. You know how inconsistent he has been at his new team. There is criticism pointing him and Ancelotti is trying to keep him focused.
You're right. In the second half, there are no more goals. Real Madrid prefers to keep their leading with 2 goals. They were likely playing with a more defensive tactic n the second half. I think it wasn't a bad idea, leading with 2 goals is enough to win the match. After capturing the 2-0 lead they got relieved probably. At least they maintained the same score until the end.

Although he doesn't score as many as goals in the previous season, but Bellingham has a crucial role in the midfield line of Real Madrid. Bellingham supports both attacking and defense line, he has more functions in his current position. By the way, Mbappe scored 1 goal, it indicated Mbappe still has good quality in scoring goals.
Atletico Madrid were also amazing with a 5-0 victory over Valladolid by the way. It is lovely to watch the title competition now. 
Top 3 are really close to each other and Real Madrid are very probable to take the lead soon.
Yep, Atletico Madrid returns to the title race now. Atletico Madrid got 32 points now, it is only 2 points difference from Barcelona point in the 1st place. Meanwhile Real Madrid got 33 points and they still have 1 unplayed match. Real Madrid possibly leads the table if they won the unplayed match. Well, La Liga title race looks more interesting now. Top 3 are really close to each other and Real Madrid are very probable to take the lead soon.
