Ex-Nigeria national team coach, Augustine Eguavoen, has said he is happy with the quality of defenders in the Super Eagles team.
He also feels that the coach, Gernot Rohr, will have a selection headache because of this.
The former manager said the coach will find it difficult to pick the required number of players for his squad for the 2018 FIFA World Cup in Russia.
Defenders such as William Troost-Ekong, Leon Balogun and Shehu Abdullahi, all helped the national team qualify from a tough World Cup qualifying group, that included African powerhouses Cameroon and Algeria.
The likes of Tyronne, Ebuehi, Ola Aina and Bryan Idowu, have also shone for their respective clubs and are strongly pushing for places in the team ahead of the global tournament.
Eguavoen, who aside from managing the team, represented the three-time African champions at two FIFA World Cups, believes a strong defence will play a key role for the team in Russia.
