It's true. You can find the news easily. Karim benzema still has a problem with his injury. He would not able to perform with his nation. This might become his last world cup if he would able giving good contribution to the france but that's very sad to see that if he must have absence from the world cup due to the his injury. He may not able to play with real madrid after the world cup due to the his injury as well. That would be so bad for him as that may give golden chance for him.
It is certain that Didier Deschamps' squad will not be strengthened by Karim Benzema ahead of the match against Australia, most likely Didier Deschamps will call Wissam Ben Yedder as a replacement for Karim Benzema, because Christopher Nkunku also suffered an injury during training. A lot of French players are injured, it will look bad for Didier Deschamps' squad, there is a bit of doubt about the squad that France has at the moment, but I think they will be able to overcome this problem, especially because France has a lot of players in all positions and is ready to replace the injured ones.
This happens when you are too much dependent on a single player. Karim is also one of key player for real madrid but France must not have too much dependency on him. Now since Karim is out from this Cup france chances of making it to next round are now too slim. This should not be the case.
