Dundee United will on Wednesday unveil Jackie McNamara as their replacement for manager Peter Houston after agreeing to compensate Partick Thistle.
Houston, 54, announced two weeks ago that he would be leaving the Tannadice club at the end of the season.
However, he brought forward his departure by leaving the Scottish Premier League club on Monday.
McNamara, 39, has guided Thistle to second place in the Scottish First Division in his second season there.
"Following an approach from Dundee United, the Board of Directors of Partick Thistle Football Club have reluctantly granted permission for Jackie McNamara and Simon Donnelly to speak to them about their vacant managerial position," said a statement on the Glasgow club's website.
He took over from Ian McCall in April 2011 and was given a one-year rolling contract with the Jags a month later , with former Celtic team-mate Simon Donnelly assisting him.
