Football is for the young amd strong. One must get old as time passes on. It's what you invested that will take you through when you are no longer cashing out from the system.
Apart from even saving or investing the money into something good, some of these our old ballers that always end up suffering at Thier later phase always fail in the area of striving to attach themselves to the sporting ecosystem as a way of remaining relevance so some funds can still be dropping even when you're no longer actively involved in the national team.
If your build the right network while you're still in your shining days as a football star, there's no way you're going to regret getting involved in the national team if Nigeria just because your later end is not talking a turn that you thought it to take. Football is a game of time and moment, the way time moves real fast, if you're not careful you might just enjoy the game forget the need to lay good foundation while you are still strong is implemented in all your plans.
