Why u didnt realize your mod of the short sleeves to all fifa fans i remember you found a solution and i tested you version with the Barca kit
The issue is that it will mean all FIFA 14 kittextures need to be replaced (because Switch/PS3 kit textures are different due to the new model, not to mention there is a slight decrease in quality of the sleeves due to the new uv map) or all FIFA 14 heads need to be moved in Blender to accompany new body models.
However, for female body/heads for FIFA 14, it should not be an issue, because they never were in the game anyway.
