Martin Devaney has left his role as Barnsley assistant coach by mutual consent.
The former Reds winger, who won promotion as a player, had been a coach at Oakwell for a decade - first in the academy then the first team with two spells as caretaker. New head coach Conor Hourihane had spoken of the need for 'fresh faces and fresh energy'.
Devaney told the club website: “I would like to thank everyone at Barnsley Football Club for the many years of support, trust and shared experiences. After open and honest discussions, the club and I have mutually agreed that now is the right time to part ways.
"Barnsley has been a huge part of my life – not only as a coach, but a player, caretaker manager and someone who has proudly worked across the academy and development squads, and I am particularly proud to have witnessed my son progressing through the academy system.
"It is an honour to have been able to represent this club in various capacities. Barnsley means a great deal to me and always will. I leave with great memories, from pulling on the shirt as a player, helping guide the next generation of Barnsley players and securing my first win as caretaker manager against Bolton Wanderers last year. The journey has been one full of immense pride and learning.
"I would like to thank the owners, especially the Cryne family Patrick, Jean and James the executive team and all of the staff I have worked alongside over the years – I am equally grateful to the players for their trust and commitment throughout our time working together. Most of all, thank you to the Barnsley supporters for their unwavering passion and support. You make this club what it is.
"I will take away valuable experiences and lessons that will undoubtedly serve me well in the next chapter of my career. I wish everyone connected to Barnsley Football Club the very best for the future. It will always be a source of great pride to have been a part of Barnsley Football Club’s history".
