Madrid can play their usual 2 striker pair with him and Ronaldo, don't need him to be lone striker. No matter what he is with ball, he'd still be better than Benzema atm. League's already gone, i don't see how Madrid will even reach the finals of CL with current attacking setup. Ronaldo while has done good in CL but his finishing in general has declined massively which if he is unable to turn around than might end up effecting his CL performances too... Benzema being Benzema, and Bale's injuries. At least Sanchez is something instead of no one. I don't see any other option who hasn't played in CL and is good enough to start for Madrid right away.
