Gone are the days of football managers in beaten-up old jumpers and cheap tracksuits; a new wave of boss now prowls the sideline and they look, and mean, business.
From Joachim Löw to Herve Renard, the men in charge are no longer afraid to express themselves through fashion. While the world's best players adorn themselves in everything from era-defining awful cream FA Cup final suits to headline-grabbing sarongs, these managers are showing them exactly what a well-dressed man looks like.
But who makes up the cream of the crop when it comes to couture? And who looks equally at home at pitchside as well as the streets of Paris? We're here to run down the most stylish managers in the world of football.
Guardiola is so sharply dressed that he's inspired an entire blog dedicated towards his sartorial elegance.
The Bayern Munich boss has built his reputation on precision, down to the very last detail; precision of passing, precision of planning, and precision of winning. Somewhat fittingly, his style reflects everything he aims for on the pitch.
It's ironic that as a player, Guardiola was anything but stylish. The Catalan-born midfielder was successful on the pitch but no more than functional in his role as an enabler for the more flamboyant around him. Guardiola would go on to play 479 games in 12 seasons for Barcelona, winning 16 trophies as part of the now-fabled Dream Team. However, it was his move to the dugout, when he swapped his boots for brogues, that his true flair for visual aesthetics became apparent.
Under Guardiola's mindful watch between 2008 and 2012, Barcelona emerged as perhaps the greatest team in the history of the Beautiful Game, winning three consecutive league titles and two Champions League winners' medals.
He emerged as football's leading fashion icon in that time too. The stylish Spaniard is no touchline-tracksuit type, instead he relies on dark or grey slim-fit suits and adds colour with a v-neck and skinny tie to go with black or brown smart dress shoes.
Now with Bayern Munich and chasing a third straight Bundesliga title, Guardiola likes to battle the cold Bavarian winters with chunky knit scarves and cardigans. Let's just hope he never turns to Lederhosen.
He's known as the Special One for more than one reason. Jose Mourinho gets it right on the pitch every time, and he gets it right off the pitch too.
The immaculately dressed Chelsea boss was the leader of a new wave of stylish European managers gracing the Premier League when he arrived at Stamford Bridge in 2004. At the time, English football was awash with badly fitting suits, baseball caps and rolled down socks; Mourinho was a breath of fresh air in open collar shirts, fitted trench coats and knitwear.
Mourinho stands out from the crowd when it comes to his wardrobe - but don't ever tell him that a manager should only be seen in a suit. "I felt that everyone was in a suit and tie, and it was time for me to make a difference," he said in an interview in 2013. "The way to do that, as it was my work clothes, was to dress very comfortably but keep elements of my style". He's adamant he wouldn't be seen dead on the town in "training shoes" either.

Now an elder statesman of the Premier League, that doesn't mean he's slacking. Mourinho lists Giorgio Armani, Ermenegildo Zegna and Hugo Boss as his favourite designers. Perhaps he should be re-named the Stylish One.

Watford's manager is one of the latest managerial additions to the Premier League and while his side may struggle to stave off relegation, when it comes to his impeccable style he's mixing with the big boys already.
The former Atletico Madrid boss had an unconventional upbringing. His mother, Carmen, was a famous actress in her home country, and three of his cousins would become singers. His aunt, Lola? She was a showgirl. No, really.
His family's love of the limelight informs not only his expressive management style but also his wardrobe. The 50-year-old's designer stubble sits stylishly next to his range of smart wear; there aren't too many managers around (we're looking at you, Tony Pulis) who can pull off a roll neck, after all.
Watford sit in 12th place in their first season back in the Premier League as it stands, which, if nothing else, proves that like their manager, there's plenty of substance to go with their style.
