It was indeed his season,but this year seems to be a different season altogether,he hasn't score enough goals as he did last season,although the season has not gotten anywhere yet,but Barcelona's Lewandowski has began to show his goal scoring abilities in the Laliga,and might move ahead of Benzema in winning the goalden boot this year.
Benzema is not playing well this season. In fact he is not completely fit. If Benzema's fitness is right, he could have scored a lot of goals this season too. But he has missed many matches this season due to injuries. And still he is not fully recovered. Lewandowski is likely to be the top scorer this season. He has managed to adapt to the Barcelona team. And consistently performing very well in every match.
Benzema's injury has been preventing him to perform so well this season. He has not yet fully recovered and that's why ancelotti didn't wanna try to play him for full time against another team. Benzema needs more time to recover from his injury. that's why real madrid needs to fine a good substitution for him when he was not able performing with real madrid. Real madrid needs a good striker like benzema. real madrid already considered some names but real needs to make sure if one of them have meet criteria like benzema.
This is the most difficult situation for now when benzema was getting injured. Real madrid needs a good striker that can handle any chance to be goals like him
