Flying Eagles coach John Obuh has said the team will step up their preparations for the defence of their AYC crown in Tunisia.
The Media Officer of the team, Samm Audu made this known from the team's camp in Tunisia on Sunday.
He quoted Obuh as saying while addressing the team: "The training will be very intensive and whoever cannot cope will be asked to go home."
"We have a big task ahead of us as we will be the team to beat in Algeria as the defending champions and so we must do everything to keep our championship."
Audu said the team will train twice a day except on match days with emphasis on fitness and tactical discipline.
"Gammarth, which is about 24 kilometres from the capital city of Tunis, is an ideal training location for the Nigeria U20s as it will allow for total concentration.
Several other teams including the Libya full international team and Stade Tunisien, who parade one-time Nigeria Premier League hotshot Orok Akarandut, are also housed in this world-class facility" Audu revealed.
He said the cold was biting and drops to near freezing conditions in the night.
"It's like getting into a fridge," lamented Flying Eagles forward Umar Aminu, who has now recovered fully from an ankle injury he suffered in a warm-up game against Benin Republic in Abuja.
However, Sunshine Stars forward Harrison Egbune said he expects the team to cope with the stinging cold.
"I played in Tunisia with Sunshine in a Champions League tie last year against Esperance and so I expected this type of weather. We will be okay," he assured.
