The Kano Pillars midfielder says the Nigeria team will get a good result away from home when they face the Lone Stars next month
Reuben who has scored a goal for the Super Eagles noted that the team is in an awesome form and is ready to get a good result in Monrovia that will make the second leg in Nigeria a mere formality.
"I am optimistic that we are going to win the match in Monrovia against Liberia on September 8th. I am so sure because the present team has been able to play together for a long time and the results will start coming from that game," said Gabriel.
"I have taken time to look at the players and everybody wants to do their best against Liberia. The confidence is building and I don't see us coming back without a win in Monrovia.
"This is not to say that I am underrating Liberia. They have a good team, but we have a better team. The thought of missing another Nations Cup has fired up every player.
"We don't want to allow that to happen again. Coach Stephen Keshi has done a fantastic job on the players especially the home based boys.
"In time past I would never have thought that I will play for the national team while still with Kano Pillars, but there is a new philosophy now and Keshi has done well to encourage the local boys.
"I know that everything will work well for us when we travel to Monrovia and in the second leg in Nigeria," Reuben said.
The winner of that game qualifies for the Afcon in South Africa next year.
