Benzema does have a good chance of becoming Pichichi this season.. hes certainly the "reference" of Madrid this season, the number 1 striker going into the season and he has alot of confidence, aswell as a selfish streak that all great strikers have.
I think Cristiano will still score goals but maybe not as many as last season when he was playing as a striker more.. maybe more a winger assist man this season cutting in onto his strong right foot shooting.
