If you want an all and all striker, look for a poacher, someone like Klose, Fabiano, (Hunterlaar), Torres, Llorente from Atletic club.
If you want, try out Soldado from Getafe, he went to AC Milan in my save, and he just left for Valencia in real life to replace Villa.
You could also look at Iker Munain or whatever. Get a seasons worth of reports to make sure he doesn't have a poor PA in your game and he's a star.
Laslty, If your interested in Big Money spending, there is always Higuain and Benzema at Real. Dzeko is a good one as well but overused.
