Hi mate, you may wanna try this on your wingers instruction
this one when you place right footed at right wing and vice versa
this one when you place left footed at right wing and vice versa
this one is the most important, set your forward like this
this will make your forward to come deep and more involve with the play
also train your wingers to have "get forward whenever possible" and your forward to "comes deep to get ball" on their preferred moves.
with this tactic when managing swansea, both of my wingers became joint top goalscorer and my forward had the most assists for the club at the end of the season.
Hope this will help you out
