It turns out the youngster, who has represented England at Under-16, -17, -19 and -21 levels, is eligible for Nigeria.
Barkley himself revealed this in a ‘Player Focus’ interview with Everton's official website, saying he was eligible for Nigeria, in addition to England.
KickOffNigeria.com understands that Barkley's eligibility comes through his father, Peter Effanga.
Effanga lives in Liverpool where he works at the Getrag Ford Transmission plant.
But a strained relationship with his father meant the youngster took his mother's surname of Barkley.
Despite admitting his eligibility for Nigeria, KickOffNigeria.com understands that Barkley, who has never been to Nigeria, is fully focused on representing England at full international level.
