It's not just Benzema, they now have at least 4 key players injured and won't be able to play anytime soon, it's a really big problem. Vinicius according to media reports is out for a month due to his injury. Losing their main goalkeeper is also quite serious. So believe me, even if their performance seems weak in the group stage of the champions league, it's definitely not because of Karim's absence
Vini is gonna leave for 4 - 6 weeks depending on how fast his recovery is. It's hard to replace vini's position. The club can only rely on bellingham right now. Im not hoping a lot from joselu caused by his performance was terrible. The reason why ancelotti puts him on the bench instead of include him as starting line up. Real madrid needs to think about how to replace the injured players as soon as possible. It's not necessary to buy the new players but madrid should consider when a lot of players were suffering injury.
This will be also hurting the club so much caused by real madrid was only able winning the game as long as it was using main formation. Bellingham is the last hope by real madrid.
Ancellotti counting on him now. Madrid has been making wrong decision by stopping to buy the new players.
