Manager Damien Duff has departed Premier Division champions Shelbourne.
The Republic of Ireland great has opted to move on despite Shels being due to play a Champions League qualifier with Linfield next month.
Duff confirmed to RTÉ Sport that he had resigned from the club this morning.
The club are currently sixth in the table, trailing leaders Shamrock Rovers by 15 points.
Duff led the Tolka Park side to a remarkable league title success last year but they have struggled to find the same form this campaign.
The Reds confirmed the development this afternoon and issued a statement paying tribute to Duff.
It read: "Damien informed the club this morning that, after much thought, he has made the decision to resign. He shared the news with the players earlier today.
"While all at Shelbourne are deeply saddened by Damien's decision, we fully respect that he feels this is the right choice for him at this time.
"During his four extraordinary years at Tolka Park, Damien transformed Shelbourne Football Club both on and off the pitch.
"The club wishes Damien and his family every happiness and success in the future. His impact on Shelbourne was transformational. He will always be one of our own, and we are eternally grateful for the indelible mark he has left on our club."
The club's co-owner Neil Doyle, speaking on behalf of the board, said: "There are no words that do justice to Damien's accomplishments at Shelbourne and what he has done for both the club and the League of Ireland.
"We look back with immense pride on his time here. As a club, we move forward with confidence, knowing that the foundations we have jointly built will underpin our continued success. Thank you, Damien, for everything."
Duff had said he would have been embarrassed if Shels had taken even a point from Friday night's clash with Derry City at Tolka Park as he questioned their motivation.
"A bad night, a sobering night," said Reds head coach Duff.
"Didn't deserve anything from it. Huffed, puffed.
"I prepared for the game today like I was a professional footballer. My wife probably cursed me at times. Three-hour siesta, ate really well, focused my mind.
"I would like to really, really know how many of my players prepared like me or as well as me, which is damning.
"There was a severe lack of energy, real flatness, severe lack of quality and you are going to get nowhere."
Since Duff took over at Tolka Park, the Reds have been on the rise, reaching the FAI Cup final in 2022.
Despite a defeat to Derry City, it represented a return to the big days again for a club which had spent so long away from the top table.
The following season they qualified for Europe before winning the title last year.
Duff, who was a centurion for Ireland and earned two Premier League medals with Chelsea, described winning the league with Shelbourne as the pinnacle of his career.
The Champions League qualifier against Linfield in 16 days' time will have a huge impact on the club's future, with massive financial rewards on offer for the winner.
That All-Ireland clash will now be played without the League of Ireland's leading character.
