that's still a pretty good training setup. Moniz is usually good for ball control, shooting and attacking never used Innaurato so new to me.
Maybe you need a larger database to get more staff? Dunno, if I had your training I'd be happy (ish) and just keep having a quick look for regen staff that might be 5 star coaches.
I'll tell you what I have noticed in FM11 (and I think I saw it in 09 and 10 too), Staff can improve/get worse just like players can. I've signed Oliver Bierhoff as a scout cos he had judging ability of 17 and potential of 17. then judging potential went up to 18 and ability was still 17 but now they're both 18...
perhaps get younger decent staff and hope they improve to quality staff?
