Bayern Munich cruised to a 6-1 victory against Champion's League rivals Porto last night. But not all eyes were on the pitch for the whole 90 minutes, as the German club's manager Pep Guardiola broke the highly dramatic atmosphere with a moment of sartorial comedy. To put it bluntly, he split his pants. A flash of upper thigh and navy boxers made themselves known as he strode up and down the touchline shouting commands at his players. SCROLL DOWN FOR VIDEO . Sartorial slip-up: Bayern Munich manager Pep Guardiola runs through tactics with his players, while ignoring the draft that has emerged at the top of his left leg . A hint of navy: Guardiola's tight-fitting trousers before the tear (left) and after the rip (right) during Bayern Munich's 6-1 victory over Porto . The Spanish tactician, who teamed his tight, grey suit with a navy pullover, black tie and crisp white shirt, joked after the clash: 'I'll have to buy new ones for the next match.' Guardiola wouldn't be the only famous face guilty of stepping into a suit that is a little on the snug side. The current trend for wearing a whistle and flute that is at least a size too small, presumably to showcase a well-honed physique, has seen plenty of stars sail a little close to the wardrobe malfunction wind. So, who's guilty of worshipping at the altar of super-tight slacks? Russell Brand. Guilty. Dermot O'Leary. Guilty. Olly Murs. In danger of restricting the blood flow. Yes, it's officially a wardrobe malfunction...but has Guardiola simply fallen foul of wearing a suit that is a little on the snug side? Blame 007: Daniel Craig wore a close-fitting Tom Ford suit in 2012 Bond movie Skyfall...and thousands of men followed the trend . And breathe! If Beckham gets the snug look just right, his fellow Essex boys, including Jeff Brazier (pictured right) are guilty of going a little too tight . The rock star's take on the whistle and flute: Harry Styles doesn't bother with a jacket but his trousers are certainly skinny, while Russell Brand goes for a second (snake)skin with his casual version of the suit . King of the second skin! Dermot O'Leary rarely wears a suit that could be described as roomy . The trend for a tighter fit has emerged in recent years with 'skinny', 'slim' and 'heritage' fits all offering a snugger-looking silhouette. Cast an eye back three years and the most recent incarnation of James Bond, in Sam Mendes' 2012 movie Skyfall, was seen wearing the kind of form-fitting suit that makes you wonder how it might have been possible to wear it AND brawl on top of a train while hurtling through Turkey. Throughout the film, an unruffled Daniel Craig sported a grey, tailored suit by Tom Ford which may have been the catalyst for other celebrities wearing a similar look. During his just-ended eight-year reign on The X Factor, Dermot O'Leary's suits have got progressively smaller, seeing him once forced to reach for a safety pin moments before presenting the live show. O'Leary said at the time: 'I remember having a wardrobe malfunction on The X Factor. 'I had this tight-fitting Alexander McQueen suit and felt the trousers rip…from pole to pole, shall we say. I just had to skilfully apply a safety pin and hope for the best. It was terrifying.' High street menswear retailer Hawes & Curtis told FEMAIL that figure-hugging clothes are no longer just for women. Not much room to give! Olly Murs, who split his trousers on stage in Sheffield in 2012, sails close to the wind again here while performing at the V Festival in 2013 . A thigh-ful! Towie stars Dan Osborne and Joey Essex are both partial to leaving little to the imagination when it comes to formal wear . Edward Smith, head of brand for the company said: 'The skinny look has taken over everyone's wardrobe, regardless of gender. 'Men have been wearing tight T-shirts and shirts for a while now - our best-selling shirt is now an extra slim one. 'Remember, men don't want to look great at the weekend and then put on a baggy old suit for the working week. The office is just as much their chance to shine, so suits have had to go through a skinny transformation as much as any other garment.' Other stars who've fallen foul of their own outfits exposing them include fellow X Factor presenter Olly Murs, whose penchant for clothes that show off his best assets saw his trousers split as he performed on stage at Sheffield Arena in 2012. Wearing a matching burgundy waistcoat and pants, the star was dancing on his knees when the fabric covering his undercarriage gave way revealing sparkling white pants. For more examples, you only have to wander to the streets of Chelsea or Essex, as the reality television stars who grace our screens on The Only Way is Essex and Made in Chelsea don't appear to own a more roomy suit between them. Towie star Dan Osborne is clearly proud of his buff body and regularly showcases it in slimline attire and Joey Essex is also partial to a tight pair of strides. While David Beckham rarely gets it wrong these days when it comes to fashion, he is definitely also a fan of a tight suit, and arguably carries it off to perfection. What do the fashionistas make of the super-snug suit? Fashion blogger Simon Glazin isn't convinced by the current trend. He told FEMAIL: 'Over the last couple of years, terms like 'super skinny' and 'ultra skinny' have been adopted by menswear retailers when it comes to suiting, and to be quite honest, they scare me.' 'There's the circulation-restricting connotations the words 'ultra skinny' bring with them but also the simple truth that a too-tight suit can be quite hideous to look at.' Men are in danger of going for a debonair look but can end up revealing way too much, he adds. 'You don't want to show the world everything you've got! 'Some things should remain, erm, under wraps. You find bigger men stuffing themselves into these skinny suits, and the results are disastrous. 'As male models get thinner, so do suit cuts, but this is NOT representative of this country. Us men with 'real' bodies need suits that don't feel restricting. And don't restrict blood flow.' Who should you go for if you want comfort and style? 'Designer labels such as Versace and Salvatore Ferragamo offer suits that have a bit of breathing room.' Let's hope Pep, Dermot and Olly are reading.
