Kolasinac defended team-mate Mesut Ozil as two knife-wielding carjackers attempted to rob the pair in north London.
The Bosnian went viral as footage appeared of him heroically risking his own life to protect Ozil, as well as both of their wives, who were reportedly inside the car.
There have been suggestions that Kolasinac deserves to be recognised for his actions, with Piers Morgan demanding he’s made captain immediately.
And following his valiant efforts, Starsport has taken a look at which other Premier League bruisers deserve the title as the hardest at their club.
Arsenal – Sead Kolasinac
Obviously. The left-back may not feature much this season if Arsenal secure a deal for Kieran Tierney but he’s already cemented himself as a Gunners cult hero after yesterday’s drama.
Aston Villa – Tyrone Mings
He stamps on people’s faces for fun, enough said.
Bournemouth – Jefferson Lerma
Just the 12 yellow cards for Lerma in his debut season in England. Also helped kick England to pieces at the World Cup last summer.
Brighton – Shane Duffy
Sent off for a headbutt half an hour into Brighton’s biggest game of last season. Triple captained himself in fantasy football. Mental.
“Sead Kolasinac has cemented himself as an Arsenal cult hero after yesterday’s drama.”
Burnley – Ashley Barnes
It takes a special kind of nutcase to scream so loud in a linesman’s face that the referee is too scared to even book them. Was once banned for seven games for tripping up another ref.
Chelsea – Antonio Rudiger
Man mountain. Could probably tackle you with his deathly stare.
Crystal Palace – Luka Milivojevic
Palace fans literally sing ‘he’ll f***ing murder ya’ about him. Weapon of choice? Dead ball from 12 yards.
Everton – Yerry Mina
Never been beaten in the air. Broke FA rules so he could dance in a betting advert. Legend.
Leicester – Jamie Vardy
Won the league for Leicester on a diet of port and Red Bull. Hasn’t stopped running since 2015. Non-league hero.
Liverpool – Virgil van Dijk
The Liverpool player you’d least want to fight you and most want to spoon you. The gentle giant could take on anyone in the Premier League and he’d do it without breaking a sweat.
Manchester City – Ederson
Wears short sleeves and has a terrifying neck tattoo. Survived Sadio Mane’s decapitation attempt.
Manchester United – Nemanja Matic
If you can handle playing under Jose Mourinho, you can handle anything – including growing up in war-torn Serbia.
Newcastle – Jonjo Shelvey
Loves a tackle, loves a cheeky elbow. *Insert obvious joke about trying to kill Harry Potter*
Norwich – Grant Hanley
Scottish. Bearded. Never worn gloves in his life.
Sheffield United – Chris Basham
Never played for a club further south than Stafford, loves the north.
Southampton – Fraser Forster
The man is 6ft 7 and gets paid to have balls kicked at him. I dare you to try and fight him.
Tottenham – Victor Wanyama
Lures you into a false sense of security by tweeting about spaghetti before shoulder-barging you into next week.
Watford – Troy Deeney
Took on the entire Arsenal fanbase by himself by accusing the Gunners of lacking cojones – yet to be proven wrong.
West Ham – Mark Noble
Effortlessly threw a West Ham fan to the floor in the centre circle. Wears Phil Mitchell pyjamas.
Wolves – Willy Boly
You need a thick skin to get through your childhood with a first name like Willy. Probably helped that he’s literally a giant.
