The 28-year-old was part of the Belgian outfit that frustrated Paris Saint-Germain into a 1-1 draw, which was a far cry from the 5-0 result in the reverse fixture.
Ibrahimovic had scored four that night and appeared irritated by his inability to rekindle such a prolific run of goals. With the resilience of John van den Brom’s team chipping away at the iconic Swede, Kljestan suggested frustration got the better of Ibra, per ESPN:
After a perfectly normal challenge, Ibrahimovic turned to me and provoked me, making a joke about my moustache.
He said, 'That really is terrible'. I responded by telling him he should think about his nose.
This is not the first time the well-traveled striker has been accused of mocking his opponents.
Chris Wright of ESPN reported an incident that saw Ibrahimovic offend multiple players from the Faroe Islands by calling them "a bunch of fisherman" in June’s World Cup qualification contest.
The outspoken forward is known for his gamesmanship and loves to wind up opposition, teammates and friends with memorable comments.
He recently teased David Beckham for liking Justin Bieber’s music, per Greg Heffer of the Daily Star. More seriously, he spoke honestly about his difficult relationship with Pep Guardiola in his recent autobiography, as reported by Jim White of The Telegraph.
Similar to Kljestan, former Marseille midfielder Joey Barton also zoned in on Ibra’s nose, per Lee Bryan of the Daily Mail. The Englishman made a "Pinocchio" gesture during the team's cup loss to PSG last season in a match that saw Ibrahimovic score two goals.
At 32 years of age, it's extremely likely that Ibrahimovic won't alter his willingness to trash talk on and off the pitch.
The charismatic player has made a career of grabbing headlines through such events. Many consider it to be a personality quirk that is part of his charm.
