Looking back into the past can be a lovely thing: Iconic albums, genre-defining films, and of course, golden football moments.
Also, it can be harrowing. I speak from experience here, as a man who thought, for much of his late teens, it was perfectly acceptable to wear a trilby - like a deli counter Pete Doherty - around a small Scottish seaside town without suffering severe repercussions.
Yes, nostalgia can be fun, but it's always there to haunt us with ghosts from the past when we least expect it.
Alongside from a stunning array of 'Cats Doing Hilarious Things LOL' video compilations, the internet has also blessed us with a plethora of images showing football managers lookin' all goofy back in their playing days.
So, here's 11 managers in some truly extraordinary snaps from back in their prime...
1. Eddie Howe
My goodness me! where to start with this absolute beauty?
Kicking us off, it's Eddie Howe looking even more cherubic than usual. The now-Bournemouth manager rocked a sensational pair of curtains back in his playing days, which could have seen him slot into boybands as high profile as 911 or BBMak.
The sharp-eyed among you might well have also noticed the giraffe lurking in the background.
Interestingly, Peter Crouch left Portsmouth at around the same time Eddie Howe joined in 2002, so that's presumably the towering striker lurking in the shadows.
2. Mick McCarthy
Straight in at number two, it's an absolute belter of Mick McCarthy picking up Manchester City's Player of the Year trophy back in 1983.
A real fashion icon of his times, McCarthy sports a sumptuous sleeveless lemon v-neck (with matching tie), alongside a smart pair of cream trousers, quite frankly putting the gentleman beside him to shame.
And what about that thick and luscious moustache, eh? Yes, I think we can all agree, 1980s McCarthy is far superior to the curmudgeonly chap who prowls the touchline these days.
3. David Moyes
Good grief! Someone give that man a vitamin C packed smoothie, and put a warm jacket around his shoulders!
The pasty-faced young chap before you is none other than David Moyes back in his playing days, looking like Mick Hucknall, if he was cast in Trainspotting.
4. Roy Hodgson
Former England manager Roy Hodgson here, looking like a Coronation Street stalwart wth a lovely new set of rollers back in his prime.
Roy the Boy had a playing career as just as eclectic as his managerial one, and spent time with South African side Berea Park as well as more mundane spells at Maidstone United and Ashford Town.
5. Martin O'Neill
Lock up your daughters! 1970s Martin O'Neill is ready to charm and dazzle with a haircut I don't quite know the technical name for.
Free of the spectacles that give him a rather bookish demeanour these days, O'Neill's piercing stare is one that means business.
The very same year this photo was taken, Nottingham Forest (the club he now manages) won a league and cup double. Lovely stuff!
6. Steve Bruce
Just look at him! Like a Northumberlandian Ronald McDonald, Steve Bruce cut quite the bold figure back in his playing days.
Here is his right at the beginning of his career, wearing a delicious Gillingham top that doesn't at all clash with those luscious, fiery locks.
The now-Sheffield Wednesday manager won a mighty three Premier League titles with Manchester United in the 1990s, and was a ferocious defender in his day.
7. Jürgen Klopp
These days Jürgen Klopp looks quite the snappy character with his thick rimmed spectacles and baseball cap, but back in his days at Mainz, the charismatic German let his hair grow cascade down his forehead like a glorious lion's mane.
8. Luciano Spalletti
Yes! Now we're talking!
Here's Luciano Spalletti back in the day, wearing an item of clothing vivacious as his 2005/06 Roma side.
The Italian never really much of an impact on the field, and presumably spent his hours outside of training modelling lavish open-necked shirts, rather spending time practicing his free-kicks.
9. Louis van Gaal
Very Partridge, this. And I like that, I like it a lot.
There's so many astonishing tales of Louis van Gaal's exploits both as a player and a manager it's hard to separate fact from fiction at times, but there's no denying he was quite the fashionista back in the day.
10. Claudio Ranieri
Some people think Claudio Ranieri's greatest achievement is winning the Premier League with Leicester at odds of 5000/1. Wrong. Claudio Ranieri's greatest achievement is this photograph. Woof.
11. Gareth Southgate
Let's round things off nicely here, with an extraordinary photograph of now-England manager Gareth Southgate, posing uncomfortably in a bed of thriving cacti.
Was it a punishment for that Euro '96 penalty shoot-out miss, or merely training for a future career of dealing with - ahem - prickly individuals at the FA?
We may never know...
