Real Madrid are up 2-1 , but that doesn't mean we've seen an impressive contribution from Karim Benzema. The first goal, a penalty kick, was garbage. The second goal was brilliant, but it was all about the other attacking players. He's given the ball away a few times and after 35 minutes, has completely failed to do anything positive. He's given the ball away a few times already, his most recent giveaway leading to Dani Parejo's goal to pull Getafe back within one goal.
His complete lack of touch and vision might have Madridistas dreaming of Edin Dzeko, the 6'3" Bosnian number nine with a silky smooth first touch for a man of his size. It's unlikely that he would have given the ball away, which again, lead to Parejo's goal.
Madrid would probably have a hell of a lot more possession at this point with him in the side, since he's adept at holding up the ball. And receiving teammates' passes without the ball ending up 10 yards from his body.
Anyway, the verdict after 35 minutes? Karim Benzema is not the answer. And if he is, you're asking the wrong question.
