Scanned Player Faces
Konami are doing face scans of players from official partners, i.e. Barcelona, Dortmund and Liverpool. Dortmund and Liverpool player faces will be included after the first update.
Player Faces Modelling
Other faces will be created using advanced modelling techniques by the Konami development team. If David De Gea is anything to base the advanced modelling on then there won’t be a lot of difference between scanned faces and the modelling.
