Louis van Gaal was rocking the sunglasses as he watched his Manchester United side toil in the first-half sun in their Barclays Premier League clash at Norwich.
The 66-year-old has not been known for his extravagance since taking over at Old Trafford, but he would not be the first manager to make a new style statement.
Here, we look at other bosses who have sported a distinctive look.
1. Tony Pulis
The Welshman must have a free first shop around the club store written into his contract when he takes a new job. Always decked out from head to toe in club training attire, Pulis has always sported a baseball cap along with matching jacket and bottoms as he has bounced up on Premier League touchline while in charge of Stoke, Crystal Palace and now West Brom.
2. Paul Tisdale
The 43-year-old has been Exeter boss since 2006 but his signature look was not known by the masses until his side's FA Cup clash with Liverpool was aired on the BBC this season. Tisdale often tops off his look with swish headwear, with a pork-pie hat his choice for the aforementioned cup tie. In 2013, the Daily Mirror labelled him the most fashionable football manager.
3. Arsene Wenger
The Frenchman recently took part in a classy photo-shoot with L'Equipe Sport and Style - but the 66-year-old Arsenal boss is better known in this country for his full-length club coat. Many times Wenger has been caught fighting with his seemingly never-ending zip and he is known for slouching down, coat drawn over his mouth whenever he watches his Gunners slipping up in the wintry conditions.
4. Brian Clough
Arguably the manager most associated with a specific look - 'Cloughie' will forever be known for sporting a plain green sweatshirt. The man who led Nottingham Forest to Division One and European Cup glory was just as well known for his trademark jumper as he was for speaking his mind while wearing it.
5. Roberto Mancini
The Italian was always going to bring an air of swagger with him when he came to England to manage Manchester City. And Mancini never disappointed. He will be fondly remembered for donning his blue and white scarf, along with his made-to-measure suits - as well as delivering the Premier League title.
