Sunday Oliseh has resigned as coach of Nigeria citing contract violations, unpaid wages and lack of support.

Oliseh, 41, had been in the job for only eight months.

Nigeria have installed Samson Siasia to oversee next month’s crucial 2017 Africa Cup of Nations qualifiers against Group G leaders Egypt.

“Your contractual violations and the interest of the nation necessitates that I tender my resignation,” he wrote to the Nigeria Football Federation.

“So little help is being rendered me in getting the players to give their best and very vital conditions and advantages to the team play are also being sacrificed… my several e-mails and others seeking your aid to effectively carry out my duties were ignored.”
