The game's producer commented on the PS3 version in PSW magazine:
Shingo 'Seabass' Takatsuka : 'The online aspect will change drastically. From reading forums we realise that the game lags a lot, but this will be much, much better on PlayStation 3. Also, offline you'll have fantastic player movements that you'll probably only notice through replays. Of course, PlayStation 3 will give us more power to enrich the actual representation of football, such as artificial intelligence, so you'll have much smarter defenders. We'll be able to put much more emphasis on the offside battle between defenders and attackers because PlayStation 3 gives us more power.'
