Sky Sports says Bruce is due to sit down with Longstaff in the coming days and tell him he is a key part of his plans for next season amid continued interest in the midfielder from Manchester United.
Bruce has now joined up with his new squad in China at the Premier League Asia Trophy, and he is expected to tell the 21-year-old he doesn't want him to leave St James's Park.
Longstaff is excited at the prospect of Bruce taking charge, and is desperate to impress the new manager and become a Newcastle regular to progress his fledgling career. And whilst it's thought he would be keen to talk to Manchester United, if the two clubs can agree on a fee, Longstaff isn't pushing for a move.
Ole Gunnar Solksjaer is impressed by Longstaff's potential, but Manchester United are not prepared to pay anywhere near the £50m asking price it would take for Newcastle to be interested in selling. United think his current worth is less than half that amount.
