Arsenal will officially announce the signing of Kelechi Nwakali at the end of the player's international commitments.
Allwell Nwakali, elder brother of Golden Eaglets' FIFA U-17 World Cup winning captain, has again confirmed that the youngster will be the third summer signing to be unveiled by the Gunners.
Last month he posted a picture on his Facebook account saying that a move to the Emirates has been completed.
He will join Swiss midfielder Granit Xhaka and Japanese striker Takuma Asano as the first three summer signings at the club.
"Any moment from now we will go to Arsenal," the agent told All Nigeria Soccer.
"They can't allow him go now because of the narrow victory in the [Afcon Under-20 qualifier] first leg against Sudan.
"We can't betray the coach [Emmanuel Amuneke] because he has been helping us in the past."
