Celtic manager Ange Postecoglou, Ross County’s Malky Mackay, Paul Hartley of Cove Rangers and Arbroath boss Dick Campbell are the nominees for Scottish manager of the year, in association with the Managers and Coaches Association.
Postecoglou has taken Celtic to the brink of the Scottish Premiership title in his first season in charge as well as lifting the League Cup.
Malky Mackay has transformed Ross County since taking charge last summer, securing a top-six finish for the first time since 2016.
Cove Rangers will be playing Championship football next season after Paul Hartley guided them to their third title in four years and Dick Campbell has part-time Arbroath in the Scottish Premiership play-offs with a second-placed finish.
The winner will be announced at the PFA Scotland awards in Glasgow on Sunday night.
