Back in the summer, Garry Monk broke the hearts of Leeds fans when he tendered his resignation in a surprise move.
He went on to take over as Middlesbrough manager, with a Premier League appointment eluding him.
Middlesbrough backed him heavily in the transfer window, but results have been mixed, and fans are getting increasingly frustrated with the manager.
At the weekend Boro lost 1-0 at home to Neil Warnock's Cardiff City, and are without a victory in their last three games, accumulating three points of a possible 15.
This has left Middlesbrough down in 13th position, 10 points off the automatic promotion spots - where many had tipped them before the season to finish.
Fans expressed their anger on Twitter towards the manager, concerned the team is not playing attractive football or picking up results - a depressing combination.
We need to act fast and decisively now we are going nowhere under Monk. His tactics are poor & his team selections are awful #MonkOut— YOUAREMYBORO (@THEREALBORO) October 21, 2017
There is no system, no style of play, no thought process at all.... the squad is there but I have no faith in the manager at all #MonkOut— Daniel Farman (@Farman14) October 21, 2017
The vitriol towards Monk from Middlesbrough supporters has caused great amusement for Leeds United fans after the manager walked out on them in the summer.
Leeds are above Middlesbrough in the table, sitting nine places higher, and right now it is looking like Monk may have made a big mistake.
