Northern Ireland may not be in the frame for qualifying from Group F but they will go in to the Portugal encounter with confidence after O'Neill secured his first win in charge.
"It was an easy squad to pick after the win over Russia. I feel it is a strong squad and a youthful one," said O'Neill.
"Portugal know they have to win to maintain their challenge in the group, but we have a chance to build on our last result and take another big scalp.
"From my point of view it's good to have the players together again when confidence and belief should still be high and it's important we try to keep up the momentum.
"Chris Baird and David Healy are still very much in my plans when they find clubs and I hope their situations are resolved sooner rather than later."
