Cook was reportedly recommended to St.Johnstone chairman Geoff Brown by Derek McInnes, who departed McDiarmid Park for Bristol City this month.
The Scottish Sun reports that Brown has already agreed to a £30,000 compensation package for the Englishman, who was a former team-mate of McInnes.
Cook has been manager of Sligo Rovers for the past four years now and guided them to League Cup and FAI Cup success last term and 3rd in the league. He also took Sligo into the UEFA Cup three years ago. This season Sligo sit in second place behind league leaders Shamrock Rovers and are in the FAI Cup Final once again.
If Cook decides to make the move across the Irish Sea to Scotland, then it is expected that his assistant Gerry Carr and First Team coach Maurice Monaghan will also make the move to McDiarmid Park.
Other candidates for the St.Johnstone job include Bohemians manager Pat Fenlon and Arbroath player-manager Paul Sheerin.
Jody Morris – currently in a caretaker capacity alongside Alec Cleland – has already intimated that he is not the man for the job. He told the Official St.Johnstone website: “I still thoroughly enjoy playing and I’m keen to do that for as long as possible. I want stay in football beyond my playing career but for the moment I want to be out there on the pitch. However, I’ll continue to work with Alec for as long as is required until an appointment is made.”
