Depends if they play deep infront of your defence or high up field near the strikers. The further up the field the less space they have to operate in and the greater the need for skills to make space for himself.
If they play deep TTF recommends: Passing, Technique, Creativity, First Touch, Decisions, Positioning, Stamina, Marking, Tackling, Strength.
If they play advanced TTF recommends: Passing, Technique, Creativity, Flair, Decisions, First Touch, Off the Ball, Anticipation, Dribbling, Teamwork, Long Shots, Strength.
I've reordered them into the order I think of most important to least.
