Looking ahead to next week’s high-profile friendly against Portugal, Chelle said the younger players bring a different dimension to the team.
“We analyse our game and we try to put some players who can make the team improve because for me and for everybody it takes one detail to win a trophy,” he told the Super Eagles media team.
“So we have to improve because I think we have to put some young players who can bring a new mentality, something new and it’s not only about a question of mentality because the group has the mentality to win but we need to put something fresh.
“Some players will come with lots of energy, they will bring something like they want to win, to improve and the national team can be this for them.”
The Super Eagles are using the friendlies to prepare for the 2027 Africa Cup of Nations qualifiers against Tanzania, Guinea-Bissau and Madagascar.
