When these four former footballers started out their careers with a twinkle in their eyes and luscious locks, it would have been hard to imagine them taking the helm of some of Europe’s most elite clubs.
One manager currently in charge of one of the most successful teams in history looks unrecognizable with a windswept quiff on his head, while a grey-haired manager with both Premier League and international experience resembles a completely new person with marvelous long, curly locks.
Another manager to lose their hair in management was once capable of growing out extraordinary ginger locks and a Premier League-winning boss used to don a magnificent short yet incredibly stylish haircut during his playing days.
So can you recognize any from their old Panini stickers? Full marks if you manage all four!
Well done if you recognized Martin Jol, with his flowing locks and very serious expression!
The Dutchman started his playing career in his homeland at ADO Den Haag before securing a move to German giants Bayern Munich.
Martin Jol spent a year in Germany before heading back to Holland where he joined FC Twente.
He then embarked on a move to England – where he would one day go into management – enjoying stints at West Brom and Coventry before returning to ADO Den Haag where he finished his career.
For many, Jol, now 66, is associated with management – along with the fact very few can imagine him with a head full of hair.
But who could have guessed? Jol, who most famously managed Tottenham from 2004 to 2007 once had incredible ginger locks.
After guiding Tottenham to back-to-back fifth-placed finishes, Jol went on to manage Hamburg and Ajax before returning to the Premier League with Fulham.
Following two years at Craven Cottage he had a short stint in Egypt with Al-Ahly in 2016.

The ex-England boss has been a manager for the last 46 years, so it is hard to imagine Roy Hodgson was ever a player.
But the now-75-year-old was once on the books at Crystal Palace. After failing to establish himself as a player, he soon decided management was his calling.
Hodgson has been at the helm of more than 20 teams, most notably for Inter Milan, Liverpool and the Three Lions.
While many associate Hodgson with having short gray hair, as a young player he sported sensational curly locks that resemble something of a Barristers wig.
I say bring it back Roy.

Erik ten hag
The former Ajax boss is currently tearing it up in the Premier League, having taken over at Manchester United in the summer.
But Erik ten Hag was a defender back in the day, racking up more than 300 appearances in the Dutch leagues.
The centre-back, who is now famously bald, once donned an impressive blond mop on his head, pictured below, during his second spell at FC Twente in 1993.
FC Twente was where Ten Hag had started and ended his playing career too, enjoying three separate stints at the club.
The player-turned-manager also had spells at De Graafschap, RKC Waalwijk and Utrecht.
It would be hard to imagine the fresh-faced youngster with the same haircut on the Old Trafford touchline today.

The 71-year-old Italian, like Hodgson, has been in management so long that it is hard to picture him as a player. But here he is, apparently being told to look serious for the camera!
Born in the Italian capital, Ranieri started his career in Rome but moved on to Catanzaro where he made more than 200 appearances.
The defender played for Catania and Palermo before hanging up his boots and moving into management.
Kitted out in his orange Roma strip with a pensive look on his face in 1973, Ranieri rocked an incredibly stylish hairstyle and looks completely different to the man who lifted the Premier League trophy with Leicester.
Ranieri has managed some of Europe’s most elite clubs, including Napoli, Chelsea and Juventus to name a few.
He is currently back in Serie A, managing Cagliari after he was sacked by Watford just three months after taking charge.
It’s fair to say Claudio Ranieri has changed a fair bit since his time as a player for Roma in 1973
