Nigeria play Portuguese Second Division club Farense in the last game of their preparations.
Despite heading to South Africa with 17 debutants, the Super Eagles go into the tournament as one of the favourites, and Keshi has reinforced that belief.
"The team on ground is well prepared for action at the 2013 Nations Cup and again I urge Nigerians to line up behind the team in a bid to bring greater glory to the country at the tourney," Keshi said, according to Media Officer Ben Alaiya.
The game kicks of at 3:30pm Nigeria time. The Eagles followed up their 0-0 draw against Cape Verde with a 1-0 victory over Dutch first division club Sparta Rotterdam.
