Hes in a league that EA do not have the rights for (Brazil League) Which i hope is back for FIFA 20 not sure though
I say that i checked his team and that team might be in career mode not sure about it but 100% not in ultimate team i loved the brazil league in fifa 12 Maikon leite brasilvers :D
Brazilian league had 218,000 votes (3rd) to get it licenced for fifa 20. "voting page"
Although that voting page is not affiliated with EA, hopefully it will be fully licenced either this year or next : )
The problem with Brazilian league is that for the way that is legally founded, EA would have to make contracts with each player, instead of with just the league/clubs.
Hope this help (if so, please hit on the XP/solution).
