Nigeria coach Sunday Oliseh Monday sent a letter of apology to the Nigeria Football Federation (NFF) after his recent  attacks on the federation as well as his perceived critics.

Nigeria failed to reach the knockout stage of CHAN 2016 leading to speculations over the future of Oliseh as Eagles coach.

Oliseh in turn fired back, saying his team were not motivated to go farther in the competition in Rwanda.

He also took timeout to fire salvos at “insane” critics, particularly his former international teammates, who he claimed have been most unfair to him with their attacks in the media.

A close source to the Eagles coach disclosed: “Oliseh has just sent a letter apologising for his utterances and actions.

“He said he is sorry, that he never wanted to attack the NFF or embarrass them, but rather he wanted the whole world to know they have not been given money.

“He also said he has been very frustrated after the heavy attack on him and his team after their exit from the CHAN.”

Oliseh’s seven months in charge of the Eagles have been marked by controversies.

He fell out with former captain Vincent Enyeama with striker Emmanuel Emenike also quitting international football during that time.

He has also gone public with the money problems affecting his team at CHAN to the embarrassment of his employers.
