Football is an emotional sport. Sometimes our passion for the game can get the better of us. And managers are no different.
They are often the bastions of authority and gatekeepers of professionalism, leading by example so their players don't step out of line.
But, not always do those on the touchline keep a cool head. Sometimes instinct kicks in and you're lost in the moment, and there is no better example of this than with an unexpected victory, a last-minute goal or triumphing over a great rival.
One look at Diego Simeone's animated theatrics, or remembering Andre Villas-Boas' touchline enthusiasm in the Premier League, will tell you all you need to know about the passion intrinsically woven into the fabric of all managers.
With that in mind, here are 10 times they let their hearts take over and went completely over the top with their celebrations.
Jose Mourinho v Manchester United
Porto's 2004 Champions League win shocked the footballing world, with absolutely nobody expecting them to get so far into the knockout rounds, let alone go all the way.
However, they did just that and in the process, they introduced us to the madness that is Jose Mourinho.
In the 90th minute of the second leg in the first knockout round, Manchester United were leading 1-0 thanks to a Paul Scholes goal. That goal meant it was 2-2 on aggregate, with Man United going through on away goals. However, right at the death, Costinha bagged a dramatic goal that gave Porto the most unlikely of victories.
In what would become typical Mourinho style, the Portuguese burst out of his seat and sprinted down the touchline to celebrate with his players and fans. It simultaneously drew the ire of the Man United fans and sealed Mourinho's place in Champions League folklore.
Pep Guardiola v Southampton
Manchester City had long since secured the 2017/18 Premier League title when they travelled to Southampton on the final day and you could have forgiven them for simply going through the motions. However, Pep Guardiola is a perfectionist and this game presented a chance for City to reach the 100 points tally, an unprecedented feat in Premier League history.
Thanks to some dogged Southampton defending, the chance looked gone as the sides went deep into stoppage time with the scores at 0-0. But in the 94th minute, City found a way, with Gabriel Jesus bagging a last-gasp winner and heading straight for the away fans behind the goal.
Meanwhile, Guardiola jumped straight out of his seat and appeared to contemplate joining the mess of limbs, before thinking better of it, instead choosing to bounce around awkwardly on the touchline with his coaching staff.
Simeone vs Juventus
The Argentine manager wanted to show that his team had the cojones needed to beat the Italian club, prompting him to turn to his fans and grabbing his crotch in front of them.
It appeared after Jose Gimenez scored the first of two late goals in Atletico's 2-0 victory in the first leg of last year's Champions League last 16 tie.
This one could've been the most offensive celebration if Ronaldo didn't imitate him after pulled Juventus back with a hat-trick in the second leg.
Alan Pardew v Manchester United
Awkward, disturbing, uncomfortable, mortifying; these are all words in the English dictionary, yet none of them even come close to describing that Alan Pardew jig against Manchester United in 2016.
It was the FA Cup final and the stakes were high. This kind of high-pressure atmosphere can bring out all sorts of crazy behaviour in people, and when Jason Puncheon scored a 78th-minute equaliser for Crystal Palace, Pardew brought out his best (worst) dance moves.
Pardew had obviously spent years getting familiar with the best of the Bee Gees to hone this particular celebration, which is reminiscent of every embarrassing uncle at his 40th birthday shin-dig, and it has since passed into GIF folklore.
Pochettino vs Ajax
The north Londoners were dead and buried at half-time in the second leg at the Johan Cryuff ArenA as they trailed the Amsterdam team 2-0 on the night and 3-0 on aggregate after goals from Matthijs De Ligt and Hakim Ziyech.
However, a miraculous comeback, spearheaded by Moura, was completed deep into added time when the Brazilian slotted home a loose ball to seal an away goals success and spark amazing scenes in Amsterdam.
He had earlier netted a brace to pull Spurs level, but his third goal – scored one second after the five allotted minutes of injury time – is what truly made him a Tottenham hero.
Mauricio Pochettino was reduced to tears as Tottenham booked their place in the Champions League final with a ‘miracle’ defeat of Ajax.
This could be one of the most touching scenes from last year's Champions League.
“It is difficult to talk. I am so emotional,” he said. “Thank you football. My players are heroes.”
Jurgen Klopp v Everton
The dramatic and bizarre nature of Liverpool's win over Everton last season sent the Anfield crowd into raptures, and it clearly rubbed off on manager Jurgen Klopp.
When Virgil Van Dijk shanked the ball high into the air in the 96th minute, everyone assumed the ball was going out and it was game over, 0-0. That was everyone apart from Jordan Pickford, who decided he would push the ball back into play, onto the crossbar then straight onto the head of Divock Origi.
The goal sent the red half of Merseyside wild, with Klopp sprinting onto the pitch and diving on his goalkeeper, Alisson. Klopp apologised for his actions in the immediate aftermath, while fans from both sides certainly saw the good and bad from his antics. You can't deny the German's passion for the big occasion though.
An FA misconduct charge was also issued to Klopp, who ultimately accepted it. The former Dortmund manager was fined £8,000. Ouch.
Diego Maradona v Peru
It was looking gloomy indeed for Argentina in October 2009. The two-time world champions found themselves drawing 1-1 at home to Peru, leaving their World Cup qualification hopes in the balance.
That was until Martin Palermo's injury-time goal secured them a vital 2-1 win, getting Diego Maradona's side right back on track.
The rain was lashing down in Buenos Aires and Maradona, who was not in the best shape of his life at the time, decided to run onto the pitch and go into an awkward belly flop/slide across the wet turf. It wasn't graceful, it was certainly ludicrous. But something about it was typical Maradona.
Jose Mourinho v Barcelona
Honestly, we could have made an entire piece dedicated to Jose Mourinho with this topic.
Another of his crazy moments came in the 2010 Champions League semi-final. Inter Milan v Barcelona was billed as a total clash of styles; Guardiola's 'tiki-taka' vs Mourinho's pragmatism.
However, Mourinho's Inter put on a totally unexpected display of attacking class in the first leg at the San Siro, coming from 1-0 down to take a 3-1 lead to the Nou Camp. That lead was reduced to 3-2 late in the second leg, but Inter held out in true Mourinho style.
When the final whistle finally sounded, Mourinho surged on to the pitch to partake in exuberant celebrations with his players, goading Barca players and fans alike and enraging the Catalan crowd. Just another day at the office for Jose, though.
