The game is the first in the series to include officially licensed British teams-Arsenal and Chelsea of England, as well as Celtic and Rangers of Scotland. The game also includes fully licensed leagues- La Liga of Spain, Eredivisie of the Netherlands, and Serie A of Italy. It was also the first in the series to include fully licensed national teams - Japan and South Korea.
