Nigeria, June 6 -- The Super Eagles held their first training session in Lisbon on Friday as preparations gathered pace for next week's international friendly against Portugal.

The team was further boosted with the arrival of Samuel Chukwueze taking the number of players in camp to 22.

Nigeria's delegation had arrived in Portugal after Wednesday's 2-2 draw against Poland in Warsaw, with 19 players making the trip as Head Coach Eric Chelle shifted focus to another stern European test.

The squad has since been strengthened by the arrivals of Alex Iwobi, Genk defender Christian Akpan and now Chukwueze, bringing the team closer to full strength ahead of the clash scheduled for Wednesday in Leiria.
