The Flying Eagles training camp in Tunisia is expected to bubble on Thursday with the arrival of three Europe-based professionals.
Flying Eagles' Media Officer, Samm Audu said the three players have been given permission by their respective clubs to join the National team at the said day.
The overseas players are; Mikel Agu (FC Porto/Portugal), Saliu Popoola Sodiq (FC Metz/France) and Edafe Egbedi (AGF Aarhus/Denmark).
They will thus complete the 30-man provisional squad recently named for the 2013 African Youth Championship in Algeria.
Sodiq featured for 36 Lion of Lagos before he bagged a contract in France.
He is widely regarded as an exciting addition to the team because of his creativity in the midfield.
Defensive midfielder Mikel Agu, who is with the Porto U19 team, has already trained with the team during their training tour of the eastern part of Nigeria recently.
Egbedi was part of the victorious Flying Eagles to the 2011 tournament in South Africa.
The Flying Eagles are expected to name a final 21-man squad for the 2013 AYC by the CAF deadline of March 6.
