It's such a big shame that a Nigerian team managed to win CAF Champions League twice, and in this ongoing CAF Champions League Rangers is the only Nigerian team that qualified to the next round, and from the look of things I don't even think Rangers can win the CAF Champions League.
It is football brother and in that game, no champion reigns forever. I understand your feeling but what we are seeing now is a sharp decline in football generally including the national team that failed to qualify for the 2026 World cup. If they overhaul the management of NFA, I'm sure something good might begin to happen to Nigerian football.
It is a big shame indeed if we have to compare Nigeria with other African countries that have won the CAF Champions League trophy.
The CAF Champions League trophy, It's now that I have found out that the North Africa(Egypt, Morocco, Tunisia, and Algeria) is the one dominating it because they have won the trophy 37 times, more than half of the total since the CAF Champions League competition started in 1964 till today.
Nigeria and Ivory Coast won twice. Guinea, South Africa, and Ghana won it three times.
