While not adding much to the game engine, the biggest new inclusion in "FIFA Football 2004" is secondary divisions, which allow the player to take lower ranked teams into the top leagues and competitions (a promotion/relegation system was present since the 2000 edition, but none up until this one featured second-tier leagues). A new gameplay feature dubbed "off the ball" was introduced, which is the ability to simultaneously control two players, in order, for example, to move a second player into the box in anticipation of a pass. The online mode was touted as the main feature. Another key feature is "Football Fusion", which allows owners of both "FIFA 2004" and "Total Club Manager 2004" to play games from "TCM" in "FIFA 2004". This is also the first "FIFA" game to feature Latin American club teams aside from those of the Brazilian League; there are four from Mexico (América, Toluca, Monterrey and UNAM; a fifth team, Tigres UANL, is present only in the Game Boy Advance version) and two from Argentina (Boca Juniors and River Plate). The title sequence, featuring Ronaldinho, Thierry Henry and Alessandro Del Piero, was filmed at St James' Park, the home ground of Newcastle United.
