The Nigerian team will now face Brazil and Portugal.
The Nigeria U20 team, the Flying Eagles, were on Wednesday defeated, 2-0, by Mexico in their opening match of the Toulon invitational tournament in France.
The Nigerian team, who are debuting at the invitational tourney, played second fiddle to the Mexican side who scored a goal in each half o get off their campaign as defending champions of the tournament on a winning note.
A poor defensive display and equally a blunt attack has seen many already raising eye-brows on the Junior World Cup bound Nigerian side who have been in Germany for some weeks to hone their skills.
A terrible defensive blunder by one of the Flying Eagles new boys, Samuel Mathias, gifted Mexican striker, Morales, the first goal in the 27th minute.
A string of saves from Flying Eagles goalkeeper, Samuel Okani, who could easily pass as the best player on the day on the Nigeria side denied Mexico the opportunity to increase their lead before going for the break.
The Flying Eagles showed some form of improvement in the second half but with nothing to show for it as they conceded the second goal in the 72nd minute off a strike from Abella.
The Flying Eagles will now have to step up for the tougher group games against Brazil and later Portugal.
