I dont know what you mean by advanced skill moves .... but you can do a lot of tricks by changing your input layout to
Mouse+Keyboard
Keyboard for movement and mouse for point and shoot (short pass, lob pass , cross etc)
For skill moves
->While moving against a defender (arrow keys) press shift , the mouse pointer should change to a shoe icon ...... Then just shake your mouse

(ready to shake a leg ? )
The direction you shake will determine the type of move he performs
For example shaking the mouse from left to right when stationary will make the player perform the cool move that Ribery performs in the intro video
