Sunderland confirmed on their official website on Sunday that manager Dick Advocaat has left his role at the Stadium of Light.
The Dutchman, 68, arrived on Wearside in March, and was charged with the task of keeping the Black Cats in the Premier League having fallen in to trouble under previous boss Gus Poyet.
Advocaat managed that task, and intended to leave the club - only to perform a shock U-turn and take the Sunderland job on a longer-term basis.
This season though, Advocaat has struggled to get things going for Sunderland, with no wins to his name before his departure on Sunday, which came just a day after his side had drawn 2-2 against West Ham United.
One team who Advocaat did have great success with is Rangers. With 131 wins in his 194 games in charge of Rangers, Advocaat won two league titles, two Scottish Cups and one Scottish League Cup before leaving in December 2001.
Gers fans took to Twitter after Advocaat's departure had been confirmed, with many passing on messages of support for the Dutchman, who remains a popular figure at Ibrox.
In fact, some fans even floated the idea of Advocaat returning to Ibrox in a Director of Football capacity, after manager Mark Warburton told BBC Sport that he would be open to working under such conditions - though it seems more likely that Advocaat will retire from football entirely at this stage of his career.
Here are some of the reactions from Rangers fans after Advocaat's departure, including those who want him to return to Glasgow in the near future...

Dick Advocaat is looking old and tired. Think it's time to retire wee man, you've had a good career - enjoy it!— Graeme (@TheGraetOne) October 3, 2015
Ibrox teaches its employees well. Advocaat resigning and waiving his salary is a touch of the sort of class you expect from a True Blue.— Danny (@Danny_RFCACM) October 4, 2015
Advocaat did great to keep Sunderland up last season. Should have left on a high.— Andy McKellar (@AMcKellar89) October 4, 2015
