It seems that for today, March 3 ( the day of the release of the Libertadores -themed DLC) we will have to content ourselves only with the Prime and Moments ICON card of Riquelme.
The first contents for Libertadores’ FUT mode are expected, according to an In-Game notice, for March 6th and presumably for 6:00 pm UK.

Certainly several players from the top South America competition will be added.
We will continue to monitor the situation and notify you as soon as we have more information.
FIFA 20 is available from September 27, 2019 on PlayStation 4, Xbox One, PC, Nintendo Switch. Keep on following us also through our social Facebook and Twitter for other news and information.
