What determines how good a player shoots?

Hi I'm new and I hope you can help me.

I was wondering what else besides shooting, technique and composure determine how good a player shoots? I'm pretty certain there's something else having a huge influence. Otherwise Robben, Ribery or Neymar wouldn't fail so many CCC. I've had them fail 7 (yes, seven) CCC in a single match and the goalkeeper had little to nothing to do because they kept shooting off target. On the other hand, Alexis from barcelona has a poor finishing attribute (12), yet he scores tons of goals without missing alot.. something similar happened to walcott while I managed Arsenal, he had poor technical and mental attributes , yet he scored alot of goals.

Thanks

It is more of the movement of the ball that decides the finishing....

When it come's to shooting,it don't really matter on the stats because if u look at Yoni Buyens stats his shooting is wack,but yet has scored screamer's from outside the box on 10 different occasion's.
Obviously certain players are born with a great shot like Gerrard,Lampard,Sigurdsson and many other player's.
