Thanks for the answer!
Yes, I have read that, but is not clear. There is a page (up to Feb 2016) I can't post the link (see below), where EA said that is allowed "Fair Use" for FIFA footage. But, you must ask for permissions for licensed content, third party things included in the game.
Search in google "How to request permission to use EA content", the first link is the right one.
About the Fair Use EA said:
EA appreciates the passion that players have for our games, and we're always excited to see the creativity that comes from our community. EA does not object to fair uses of video footage or screenshots on video sharing sites, including YouTube channels that are commercialized, as long as the footage is a version of the game that we have released to the public.
As far I can understand, is fine. But you must don't use third party things, for example, music. For that, you must ask a permission.
I'm quite new in freedom so, I ask this because I didn't know if there is a "correct" answer about this issues outhere. In the forum search didn't find too much info.
I hope we help each other sharing this info.
