Fifa has issued ultimatums to Nigeria and Ghana that they both face bans from global football for “undue influence” in the affairs of their governing bodies.

Nigeria’s ban could begin with immediate effect if the Nigeria Football Federation “offices are not handed back to the legitimate NFF executive committee under president Amaju Pinnick”.

The issues in Nigeria come after a recent court case recognised Chris Giwa, who is currently banned by Fifa, as the NFF president.

Giwa has been protesting the result of elections held in September 2014 that saw Pinnick installed as NFF president.
