How to improve my striker's performance

artilheiros

I'm using Genoa and my fowards are Milito and Cardozo. Actually they are not playing well as I expect (rating is 6.8 ~ 6.9). Cardozo is still ok, he has played 12 games with 7 goals (but 3 of them are penalty). Milito has scored only 4 goals after 10 games.

Because both of them are striker, I want to know how to setup the foward run for them? And what's the different between often and normal for setting the forward run  for a striker?

thx
