Being the manager of a football club is one of the most difficult jobs in the world. From the minute you take charge of a new team, the pressure is on.
Thankfully, for many, there aren't always too many minutes to endure.
This week, Gennarro Gattuso left Fiorentina after just 23 days in charge and without even playing a game. Impressive, in it's own horrifying way.
With Gattuso as inspiration, let's take a look at some of the shortest big-name managerial reigns.
Brian Clough - Leeds United (July 1974 - September 1974)
While Clough was undoubtedly one of the greatest managers of all time, it is fair to say that his reign at Leeds United never worked out.
This appointment was a huge surprise in the first place considering some of the things he had said about Leeds in the past, including calling their style of play "dirty" and "cheating."
Clough only lasted 44 days as manager of the club. During that time he took charge of eight matches, winning one, drawing four and losing three giving him an unwanted win percentage of only 12.5.
He was unsurprisingly sacked with Leeds sitting in 19th place and having led them to their worst start to a league season for 15 years.
Steve Coppell - Manchester City (October 1996 - November 1996)
This one was just simply bizarre. Coppell had left Crystal Palace to become the new manager of Manchester City.
However, after only being in charge of the club for a short total of 33 days he ended up walking away from the job due to deciding there was too much pressure on him.
He only managed the Citizens six times, winning two, drawing one, and losing three giving him a win percentage of 33.33.
Coppell's short reign at City remains the shortest in the club's history.
Jacques Santini - Tottenham Hotspur (June 2004 - November 2004)
Does anyone reading still remember Santini's time in the Tottenham dugout? Well, you will be forgiven if have forgotten.
He joined the club after leaving his position in charge of France's national team at the end of Euro 2004. Hopes were high when the Frenchmen first arrived, but sadly for the North London side, he only ended up taking charge of 13 matches.
Unfortunately, Santini's main reason for leaving Spurs was due to having personal problems at the time. However, it was also rumoured that he had plenty of disagreements with at the time Sporting Director Frank Arnesen.
Out of the 13 games he oversaw, he won five, drew four and lost four giving him a win percentage of 38.46.
Roy Hodgson - Liverpool (July 2010 - January 2011)
Yes, this turned out to be a complete disaster. In fairness to Hodgson, though, he did not become Liverpool manager at a good time for the club.
The veteran took charge in July 2010 while the club were up for sale, so some struggling times were inevitable. However, under Hodgson's leadership they were even worse than expected.
His time on Merseyside just never got going and at one point, he unforgivably had them in the relegation places.
He was eventually dismissed on 8 January, 2011 with the club sitting down in 13th place in the Premier League table.
Overall, he managed them 31 times, winning 13, drawing nine and losing nine giving him a win percentage of 41.9.
Gary Neville - Valencia (December 2015 - March 2016)
This appointment was always going to be a risk due to Neville's lack of managerial experience and, unfortunately, it was one that did not pay off.
In truth, the former Manchester United right-back's time in Spain turned out to be a disaster.
In his first game in charge of the club, he led them to a 2-0 defeat against Lyon, eliminated the Champions League at literally the first attempt.
That one wasn't really on him, but he also infamously guided them to a humiliating 7-0 loss at the Camp Nou against Barcelona in the Copa del Ray .
Unsurprisingly, Neville was relieved of his duties with the club sitting in 14th place in La Liga and Gary Neville has never returned to management since.
Tony Adams - Granada (April 2017 - June 2017)
Well, the less said about this managerial reign the better.
The former Arsenal captain took charge of the La Liga strugglers with seven games remaining and went on to lose every single one of them which of course, condemned the club to the drop.
Adams was inevitably sacked at the end of the 2016/2017 campaign.
Frank de Boer - Crystal Palace (June 2017 - September 2017)
It is easy to forget that this appointment ever happened but, unfortunately for Palace fans, it did.
While it could be argued that Frank De Boer deserved more time than he got, the Dutchman's time in South London was a major flop.
He only managed the club on four occasions in the Premier League, but they all ended in defeat with Palace failing to score a single goal in any of them matches.
He did gain one win in charge which was a 2-1 victory against Ipswich Town in the first round of the Carabao Cup.
De Boer is, of course, currently coaching the Netherlands at Euro 2020 and doing it to fine effect.
Julen Lopetegui - Real Madrid (June 2018 - October 2018)
Well, this did not go according to plan for Real Madrid or Lopetegui.
Just before he was set to lead the Spanish national team into the 2018 World Cup, it was announced that the former goalkeeper would be taking charge of the 13-time Champions League winners once the tournament had finished.
However, in a rather famous incident, he was then sacked as the manager of Spain just two days before their first group stage match against rivals Portugal.
If that was not bad enough, his time in the Real dugout arguably went on to be even worse.
His reign turned out to be dreadful and he only took charge of 14 matches in total. Out of them, he only won six.
