It is possible to get your wingers to track back, however you must consider the following...
They need high stats in Team Work, Work Rate, Marking, Tackling, Concentration, Positioning Stamina and Decisions.
Leave them on Mixed Forward Runs, which will allow the to get forward when need but also able to track back too...
Marking would need to be on Man and tick Tight Marking, but by doing this if you regain possesion, it will leave you with very limited options to play the ball forward, so think very carefully about how you would have to adjust your tactics to counter-act this...
