Producer Matt Prior said that the Wii U edition sits somewhere between FIFA 12 and FIFA 13 in terms of features.
"We have to take a point in time when the game's stable and then bring it over and then all the work we're building on top of it, so in terms of where this is at, it's not 12, because there's a lot of enhancements from 12, it's not 13 - it's kind of somewhere in between at a core level," Prior told Nintendo World.
"We wanted to make sure we got the most popular feature in versions for the 360 and PS3.
"Either online or offline, the most popular feature in it is an online mode called Online Seasons, so that's in the Wii U version.
"Some of the more advanced modes that took many years to kind of come onto 360 and PS3, things like Ultimate Team, they aren't on it at launch, but the biggest one in terms of popularity is," he added.
Prior also revealed that the Wii U version would feature improved pitch textures, as well as enhanced crowd visuals.

Users will be able to easily switch between players on the pitch, better direct passes and shots, and take precise penalty kicks.
The Wii U version will also feature an enhanced manager hub, enabling users to tap on any player to view their statistical analysis.
Team tactics can also be adjusted using the touchscreen, as well as an unclear feature for providing team talks at half-time to motivate specific players.
FIFA 13 will first be available on Xbox 360, PS3, PC, Wii, 3DS, Vita, PS2, iPhone and iPad from September 28. The Wii U version does not have a release date yet.
It is expected to launch alongside the console, however.
