Real Madrid's performance is not as poor as we expected to see from Real Madrid without Benzema. It is true that Real Madrid have some weaknesses in attack. However, since Bellingham is performing well, the weaknesses of the attack are not yet understood. If Bellingham performs poorly in a match, perhaps Madrid will understand the weakness of the squad.
Real Madrid lose Benzema. Vinicius is out of the squad due to injury. Both of these players have consistently performed well in Real Madrid's attack last season. So without these two players, Madrid's attack is likely to be weaker now. Also Luka Modrich is old enough. He probably won't be on the field for the full 90 minutes. So Madrid's attacking performance will now depend on Bellingham, Joselu and Roadyrgo. Madrid's next match is against Sociedad. Winning this match is challenging for Madrid.
It's not a situation that can last forever for Real Madrid without a strong striker who scores goals at full speed. He can run for cover but when the game gets tough between the Champions League and the Championship he will be in extreme difficulty, you'll see if I'm not wrong.
They need good attacker like Osimhen
Real Madrid need a proven scorer like Osimhen or Mbappe. Benzema was a regular scorer for Real Madrid. And Vinicius, Rodrygo and JOselu are talented and experienced no doubt. But they are not regular scorers. Joselu played very well with Espanyol last season. He has scored many goals. He was probably the third highest scorer in La Liga. But his performance with Madrid is still not very good. On the other hand, Vinicius and Rodrygo cannot even score on a regular basis. So next season Madrid management must add experienced striker to the squad. Perhaps the Madrid management should add Osimhen or Mbappe to the squad.
