Chukwueze suffered serious injuries in May 2021 and was forced to miss at lest five months of action for Club and Country.
The Villareal winger last played for the Super Eagles against the Crocodiles of Lesotho at the Teslim Balogun Stadium back March 21.
The winger trained with his teammates and the Napoli winger took to his social media handle to welcome him back to the squad.
“Welcome Back Brother (Chukwueze)”, Osimhen posted on Twitter.
Osimhen and Chukwueze are members of the Golden Eaglets squad that won FIFA U17 World Cup for Nigeria in Chile six years ago.
