In 2014, and 2015, a glorious mobile app existed: Fifa 15 Ultimate Team, and Fifa 15 Ultimate Team: New Season. This allowed us to play Ultimate Team on the go, with a few other fun weekly match modes. There were glitches, but overall, it was great, and very similar to the console edition of FUT. Me and my friends loved it back then, I remember a friend of mine getting a glitched out Messi CB, which was downright hilarious, or me getting a Mo Salah Roma Hero card. Later, the app was changed, to the Fifa Mobile format. Fifa Mobile isn't horrible, but it certainly doesn't stand close to the glory of Fifa 15 Ultimate Team (mobile). As I thought more about this, there should be a way that EA could link your main console FUT team with a mobile team in the app, similar to how Fortnite allows players to access profiles on their mobile devices, and EA could have players gain packs and cards for their team's on the go. It's a win-win, as FUT is EA's most popular (and the mode EA pays the most attention too), and Fifa 20 (or 21 if it takes a bit of time) Ultimate Team Mobile would be great for the loyal FUT community, who now could play it anywhere! 

Come on EA, if you're not going to change Career Mode, at least give the fans the ability to play actual Ultimate Team on their phone.
