Ambrose has not played for the Super Eagles since Nigeria's 1-0 loss away to Egypt in a 2017 Africa Cup of Nations (AFCON ) qualifier in March 2016.
Since then, the defender has not been called-up but he insists he still has a lot to offer to the Super Eagles.
“I have not retired from the national team,” Ambrose told .
“I love Super Eagles and will always support my country whenever they play. I love what the coaching crew are doing with the team and all I have to do is work hard to earn a recall.”
The 28-year-old was a regular in the Super Eagles under Sunday Oliseh before the manager resigned in February 2016.
He was invited by the then interim boss Samson Siasia for the double header against Egypt in March 2016 for the 2017 AFCON qualifiers.
Salisu Yusuf didn't invite him when he took over as temporary boss for a couple of friendly games while Gernot Rohr has prioritised other options since he took over.
Ambrose has 51 caps for the Super Eagles and was part of the squad that won the 2013 Africa Cup of Nations (AFCON) title for Nigeria.
