George Ilenikhena and Akor Adams both missed training on Sunday, raising doubts over their availability for the match in Bissau.

The two strikers featured in Nigeria’s 2-1 win over Madagascar last week but failed to finish the game. Adams was substituted after just over an hour, while Ilenikhena was taken off in the 69th minute.

Their latest injury concerns come at a difficult time for Nigeria, with Victor Osimhen already missing out of the squad through injury.

Coach Eric Chelle, however, still has other options in attack. Taiwo Awoniyi and Tolu Arokodare both came off the bench against Madagascar and could be handed starting roles if Ilenikhena and Adams are unavailable.

Moses Usor is also pushing for a place in the starting XI after scoring off the bench against Madagascar.

Wilfred Ndidi and Alex Iwobi are expected to continue in midfield, while Ademola Lookman and Samuel Chukwueze could provide attacking support from the flanks.

Stanley Nwabili is expected to keep his place in goal, with Arthur Okonkwo still waiting for his Nigeria debut.

Chelle could also make changes to the defence after most of his defenders played almost the entire game against Madagascar. Bright Osayi-Samuel could come into the starting XI to provide fresh legs.
