Super Eagles coach, Gernot Rohr, has insisted he will not bring in new players for the 2019 Africa Cup of Nations (AFCON) in Egypt.
The three-time African champions will make a return to the tournament after missing out on the previous two editions in 2015 and 2017.
The 65-year-old gaffer has mostly stuck with the players that went to the World Cup in Russia 2018, where they were eliminated in the group stage.
Rohr admitted concerns with his first-choice goalkeeper Francis Uzoho but he is unwilling to bring in a new stopper.
“We have a little challenge because our young goalkeeper Uzoho has not really played at his club this season,” Rohr told BBC Sport.
“Uzoho made one mistake in the last qualifier (against Seychelles) but we gave him a chance with the youth under-23 and it was good for his confidence.
“Daniel Akpeyi is playing now for a big team in South Africa and doing very well.
“Our third goalkeeper Ikechukwu Ezenwa is good so we can work harder with them.
“We have a good spirit as a team since the World Cup, so there’s no time to bring in new players.”
The Super Eagles qualified as group leaders during the Afcon qualifiers despite missing two of their most experienced players in John Obi Mikel and Victor Moses who retired after the World Cup last summer.
Although the former Gabon coach acknowledged shortcomings in his young team, he is hoping they can secure the continental title in Egypt.
“We can work on every aspect to improve the team, that is why we have the friendly matches,” he added.
“We qualified without two of our most experienced players in Obi Mikel and Victor Moses.
“I know what pressure is because I have experienced it with Gabon as hosts in 2012 – so this (challenge) is nothing new.
“For the World Cup our president said we could go to the semi-finals but we saw what happened.
“Now in Egypt, he says we have to win it.
“We work now to make a great tournament then we take it from there.”
