African champions nigeria u 23 defeats brazil counterpart

I think there may be some confusion here.

Nigeria's U-23 team, also known as the Dream Team, has not defeated Brazil's U-23 team in a major tournament. In fact, the two teams have a rich history of competing against each other in international football competitions.

The most notable encounter between the two teams was in the 2008 Beijing Olympics, where Nigeria's U-23 team, led by Samson Siasia, defeated Brazil's U-23 team 6-5 in a penalty shootout after the match ended 1-1 after extra time. This was a historic upset for Nigeria, as they won their first Olympic gold medal in football.

However, in more recent encounters, Brazil's U-23 team has had the upper hand. In the 2016 Rio Olympics, Brazil's U-23 team defeated Nigeria's U-23 team 2-0 in the quarterfinals.

So, to clarify, there is no record of Nigeria's U-23 team defeating Brazil's U-23 team in a major tournament.
