It cannot be denied that Bellingham's performance helped Real Madrid win, but if we look at the course of the match, I think the other Real Madrid players have very high enthusiasm and effort in pursuing victory. They didn't give Barcelona much space to build attacks and this tight marking strategy looks quite effective. 2 players who I think also deserve appreciation are Dani Carvajal and Eduardo Camavinga.
It's unbelievable to see Jude Bellingham scored again for Real Madrid and even made two goals in his first El Classico. His general performance for Real Madrid in this season, so far is very outstanding and he worth every cent spent by Real Madrid to buy him from Dortmund.
Of course, this win is from all Real Madrid players as they played as a whole team and won it as a team at the end. I agree that all players in Real Madrid who had chances to play in the El Classico, contributed to this important win for Real Madrid, not only Jude Bellingham. With two goals from the match, Jude Bellingham again will be called as a best scorer of the league with 8 goals.
There are many scorers who are behind Jude with Griezman is a closest scorer on the scorer ranking with 7 goals. Many other players have 5 goals including Robert Lewandowski who still is one of most dangerous competitor against Jude Bellingham.
