Well before predicting, I must say that this match is gonna really be tough for Nigeria based on the rating of the club that they will be playing against, but at the same time, they must win because they knew how much NFA has invested in this match to make sure that they convinced  A.Madrid to release their players to play against them. And also, they can't afford to disappointing their million fans that will be watching them all over the nation, though I don't believe that is a true taste of the level of their preparation towards the upcoming world cup, because A. Madrid will be playing for Fun which may hamper perfect assessment.

Prediction:
Nigeria will score first through set-piece
Nigeria 2:1 A.Madrid
