Celtic are battling to keep assistant manager John Kennedy from joining Ange Postecoglou at Tottenham.
It is understood the Australian also wants coach Gavin Strachan and analyst Greg Wallace to join him in north London when he officially takes charge on July 1.
Postecoglou was appointed Spurs head coach on Tuesday after two years at Celtic in which he won back-to-back Scottish Premiership titles and a domestic treble this season.
Kennedy, who had been a first-team coach and then assistant to previous managers Neil Lennon, Ronny Deila, Brendan Rodgers and Postecoglou, is believed to be keen on a move to the Premier League club.
The former Hoops player - who had a 10-year spell cut short by a serious knee injury - was also Celtic caretaker boss in 2021 following Lennon's departure.
