Postecoglou is compared to Brendan Rodgers in the manager evaluation.
David Martindale believes Livingston’s game against Celtic on Saturday will be no less difficult with Brendan Rodgers back in charge, taking over from Ange Postecoglou.
The Northern Irishman took over the Parkhead hot seat for the second time in the summer following Postecoglou’s departure to Tottenham after winning the domestic treble last season.
Celtic have been knocked out of the Viaplay Cup but are already top of the cinch Premiership by two points after five games.
And Martindale expects a typically tough encounter when they visit West Lothian under the guidance of the former Liverpool and Leicester manager.
The Livi boss told Sky Sports Scotland: “First and foremost, they are two top-class managers, so they have lost a top-class manager through success but also recruited a top-class manager.
“There is differences, subtle changes, subtle tweaks. They have lost Cameron Carter-Vickers (to injury) which has weakened them and I think Jota leaving them weakens them.
