Things are going on well for Real Madrid. They are deprived of 3 important members like Courtois, Militao and Vinicius Junior. But this is still not an obstacle for them to maintain a winning streak. Bellingham is playing a huge role in this form of course. He is even the current leader in top scorers table. 
Madrid have found their replacements. Kepa for curtois, Rudiger for militao and joselu can still play to replace vini even though joselu was not as good as vini. In fact, madrid is also having bellingham at this moment to replace benzema. It's not a problem for the club to lose those important players due to the injury. That's why madrid needs to learn from this case if the club must have also good backup once the main players were injured.
However I'm wondering how good they will deal with big opponents without these players. I mean especially the matches against Barcelona and Atletico Madrid. They are going to take on Atletico Madrid very soon for example. The reason why I wonder this is that it wasn't really easy for them to defeat Getafe home.
I think that even if madrid was losing against the big club and it's not a problem. Despite facing tough competition from top clubs like Barcelona and Atletico, Madrid still has a chance to emerge victorious. The injuries of some players did not result in Madrid completely losing its power. Madrid can also get draw against a strong opponent. Madrid just need to puts more attention to the barcelona.
