few shots on target?

My strikers seem to be getting pretty few shots on target. Example: last game was a cup match against a lower league team, over 90 minutes i got 26 shots, only 7 of them on target. It's not because it's all long shots; 'only' 12 out of 26 were in fact long shots. My strikers have 17 & 16 on finishing. Does anyone have an idea as to why they're missing so many chances and what i should alter to improve these stats? (we did score 4 that game, but i've seen other games where we didn't put away any chances :-) )

I'd suggest telling them to not take so many long shots. 12 in one game is still quite a lot. Perhaps a slower tempo as well; 26 shots sounds a little bit like they might be rushing instead of taking their time with the build-up. I'd imagine this would be much more effective against a lower quality team, as they're more likely to be pulled out of position and leave gaps for your strikers to nip in and score.
