The stopper has suffered more misfortune than most in recent years, as he's struggled to get his Nigeria career off the ground.
He made his debut for the national side in a friendly against Mexico ahead of the 2014 World Cup, and while he impressed—making a case for inclusion in Brazil—injury ultimately cost him a spot on the plane.
Stephen Keshi opted to look elsewhere in subsequent months, and the versatile defender didn't return to the fold until he started in the defeat to Uganda in March 2015, before featuring in fixtures against South Africa and Chad later that year.
He was originally overlooked for the squad to face Egypt in the ill-fated double header in March, and while he was recalled following a u-turn by Samson Siasia, injury ultimately prevented his contribution.
Leon may have missed out on Nigeria's sad failure, but he could well be set to become a key figure in the Eagles' future…at least if the misfortune that's affected him to date finally disappears.
