Concise News reports that the 30-year-old’s impressive form earned him a call-up during the 2018 World Cup qualifiers, but he did not find the back of the net on his debut against Algeria in November 2017.
He rejected big money offers from China to stay competitive in Europe and joined Turkish club Trabzonspor last August, but despite registering 10 goals and six assists in 24 appearances this season, he remains in the international wilderness.
Super Eagles Head Coach Gernot Rohr continues to select players from Turkey, Israel, China as well as the English and German second-tiers in his present squad.
However, Nwakaeme says playing in a less glamorous place could possibly be the only logical reason for his lengthy omission.
“Probably because I don’t play in a big league or for a big European club counts against me in the eyes of the coaches,” he adds when speaking to BBC Sport.
“Maybe if I’m playing for a club in England, Spain, Italy or France I wouldn’t have been treated that way.
“Personally, I’m happy with my life and career, if another chance comes up to play for my country that’s fine but if not I will continue to stay happy at my club.
“It was the fulfilment of a childhood dream when I played for Nigeria and I will always support those selected by the coach.”
Nwakaeme, who began his European career in Romania, had a successful three-year spell at Hapoel Be’er Sheva winning three successive league titles as well as lifting the Israeli Cup twice.
He scored 43 goals and created 24 assists in 120 appearances for the club after joining from rivals Hapoel Raanana in June 2015.
It was his form in Israel and UEFA Europa League that led to a call-up to the Super Eagles squad for their 2018 World Cup qualifiers in August 2017.
Nwakaeme was an unused substitute in three games before making his debut against Algeria in November.
Unlike his compatriot and then clubmate John Ogu, he was omitted from the final squad for the 2018 World Cup in Russia.
