Boss David Moyes has brought reserve-team players such as Ethan Robson and George Honeyman to training sessions.
“They can definitely do a job,” Anichebe told BBC Newcastle.
“They were so sharp, and if any of them need to be called upon they can come in and do the job.”
Anichebe, 28, worked with Moyes at Everton having come through the academy to make his first-team debut as a teenager at Goodison Park, following the path of team-mates such as Tony Hibbert and Leon Osman.
With Lynden Gooch, 20, handed his first Premier League start this season and several academy players blooded in the EFL Trophy, the same trust in youth has continued at the Stadium of Light.
“David Moyes is not afraid to use young players if they’re good enough, they’ll come in,” Anichebe continued. “That’s the whole part, it’s how young players get their chance.”
Moyes signed Anichebe following his release by West Bromwich Albion on a deal until the end of the season.
