ok here is the instruction .
1 - use afs explorer
2 - in the rar you got the hair cut and the face first insert the hair cut , on afs explorer search for hair21044.bin in your 0_text.afs , click on it and import palermohair.bin
3 - to import the face , I suggest to replace y108.bin (it's the face of a U23 japan player wich is only avaible in winning eleven 8 plus he has special face avaible) . it the same operation than for the hair you just import palermoface instead . be carefull when you search for y108.bin you will find facey108.bin redo the research to find y108.bin
4 - in game you go on edit player , choose palermo and chose for him the skin color number 3 of preset face the find the face number 108 . the hair cut is one of the animal bonus special haircuts one .
