Anyway, Real Madrid currently have Bellingham who can certainly guarantee good results in every match of Real Madrid this season. Indeed, Bellingham is not a pure striker but in fact, at this moment Bellingham is at the top of the La Liga top scorer list. So with that said, Real Madrid attacking line will remain fine at this moment and I personally do not doubt the quality of Real Madrid. Although indeed, this season Real Madrid are without Benzema and also, at this moment also Vinicius is injured. But I am sure, it will not make Real Madrid weak. Because I am sure that this era will be the one where Real Madrid have a new star, and he is Bellingham.
Actually, Bellingham can't guarantee to give good results in each match. We don't know how far he can maintain his good performance. Sometimes, a performance of a player can change toward the middle of the season. Moreover, if Real Madrid will play against stronger teams, Bellingham can get difficulty to score goals. We ever saw this when Real Madrid played against Barcelona in pre season, Bellingham couldn't contribute anything. It is not impossible to happen again in the next few matches. So, Real Madrid can't only rely on Bellingham for scoring goals.
Real Madrid still can't get the proper replacement for Benzema, Joselu isn't in the same level as Benzema. It is very unfortunate Real Madrid failed to sign a top striker to replace Benzema's role. If Real Madrid can sign a top striker, I'm sure Real Madrid attacking will be more productive in scoring. Anyway, Vinicius has a big role, losing him in the starting line up surely drops the power of Real Madrid attacking. So far, Real Madrid still could win because they didn't play against strong teams yet.
