When I'm looking to improve wing attack (you can see the two wingers I'm using now in the other topic... solid winger / passable-solid passing), where should I start? I know there is a lot of gain to be found with offensive wing backs (I train defenders, so I could buy accordingly... they can be expensive, doesn't matter, I'll make it back in the long run), but what kind of skill would I need most in a wing back? Defending obviously, I don't want to leave a gaping hole in my defense as it'd surely be punished in my league.
So what do I need then... a guy with high defense AND high winger? Do I need passing as well to make him useful offensive, or does the winger quality alone make up for most of the offensive strength? I know they need stamina, but what else is important?
Or... should I look the other way, and do I need Wingers to improve my attack further rather than Wing Backs? As you can see my wingers are pretty offensive already with their side stats, and to improve my attack further I feel like I'd need to spend a LOT of money to get a noticable difference. So I tend to think wing backs would be the way to go for me, correct me if I'm wrong please

In short, here's the main question again: If I want to improve my attack ratings, what qualities do I need in a wing back?
Thanks in advance for any help you can give
