Tam Courts has stepped down as Dundee United boss to "explore other options" after leading the club to their highest place finish in nine years.
The 40-year-old, who took charge last summer, had been linked with a move to Croatian side Rijeka in recent weeks.
But they were not willing to pay the compensation Dundee United required with the club saying he now wanted to "explore other opportunities".
Courts led Dundee United to their highest-placed finish in nine years, securing European football for the first time in a decade.
In a statement on the club's website he said: "I'm immensely grateful to everyone at Dundee United for the opportunity they gave me to manage such a prestigious club.
Tony Asghar took a chance on me and I had terrific backing from the owner Mark Ogren, the exec team and from my backroom staff such as Liam Fox and Adam Asghar.
"A special thank you must also go to the players who have been a joy to work with and a pleasure to lead. They give maximum effort to everything they do for the club and I hope they have continued success for next season and beyond.
