Agu in Abuja said that the advice would make the team to progress to the semi-final stage.
Agu said while reacting to the Super Eagles 2-0 victory over Ethiopia that it would have been unthinkable if the Ethiopians had sent the Eagles packing from the tournament.
The current Goalkeeper-Trainer of the Flying Eagles said the squad had the capacity to confront any team in the quarter finals, be it Cote d’ Ivoire, Tunisia or Togo.
Agu urged Goal Keeper Vincent Enyeama to be more focused now that the tournament had entered the knockout stage.
He said that any momentary loss of concentration could deny the team victory in the quarter finals, adding that with more determination, the eagles could surprise their next opponents.
Mr Godwin Bamigboye, the Chairman, Nigeria Coaches Association, FCT Chapter, said the team needed to work hard on their scoring skills to win the trophy.
“We are going to face the next challenge – Cote d’ Ivoire, and that is a good team.
“The players have tried so far but they need to work on their scoring. Our team is not the scoring type and that is a big problem.
“That is the area we need to work on, but I congratulate Keshi and the boys for coming this far,” he said.
Danladi Nasidi, Coach of the Under 15 National Team, said there was need for the players to be focused and hardworking.
“There is no laziness in football. All the players have to be focused because there is no individuality and laziness in the game of football.
“All the departments have to work harder. Let all the departments cooperate. The mid fielders, defenders, attackers, have to work together and concentrate.”
The Chairman, FCT Football Association, Musa Talle, commended the team for the victory and urged Nigerians to continue to support and pray for them.
Talle said the team would have no excuse not to win the cup, having reached the quarter final.
“All they need to do is to keep improving on their games.
Mr Mathew Abraham, a Special Adviser to the Kebbi State Governor, said the win was heart-warming but that Super Eagles needed to dictate the match from the outset.
Bashir Meyere, a journalist, said the eagles must rekindle the zeal to dictate the pace of matches.
“We thank God that the team showed maturity and guts to win but the match against Cote d’ Ivoire must be won convincingly,” he added.
The Enugu State Chairman of Sports Writers Association of Nigeria (SWAN), Mr Nobert Okolie, advised Keshi to work on the team’s defence, to move forward.
“It was a good match. The coach is building a new team for Nigeria but he needs to do more in the area of defence.
“Defence has been our major problem. Keshi should look into the direction of home based players,’’ he said.
Mr Okey Umahi, a businessman, expressed delight that the Super Eagles broke the jinx of playing draws in their previous matches.
“I am happy we broke the jinx of eating draw soup. Keshi should tighten his belt because the team will face Cote d’Ivoire in the quarter final,’’ he said.
Another fan, Mrs Chieso Aniwagwa, hailed the team for its victory and urged them to work harder to win the cup.
