The sports community is in deep sorrow following the untimely death of a prominent manager, who passed away at the age of 44 due to a heart attack during a game in Serbia.

Mladen Zizovic tragically collapsed on the sidelines just 22 minutes into the match between Radnicki 1923 and Mladost on Sunday evening, leaving fans and players in shock.

Despite receiving immediate medical attention and being rushed to the hospital, the news of Zizovic’s passing reached his team, leading to heart-wrenching scenes on the field as players and coaches struggled to come to terms with the loss.

Video footage of the incident, which surfaced on social media by Monday, captured emotional moments as teammates consoled one another, visibly shaken by the tragedy.

The match had initially been paused following Zizovic’s collapse, but it resumed after he was taken to the hospital. However, upon receiving the grim update, the referee made the decision to call off the game.

After the players received the news, the referee abandoned the match.

Zizovic, who was taking charge of just his third game at Radnicki 1923 following his appointment on October 23, retired from his playing career in 2016.

The Bosnian and Herzegovina Football Association also offered their own tribute to Zizovic, writing: ‘The Bosnian and Herzegovina football community lost another true sports worker today. Football coach and long-time player for Bosnian clubs, Mladen Zizovic, passed away at the age of 44.

‘During his rich playing career, Žižović played for numerous clubs in our country, among which HŠK Zrinjski Mostar, FK Radnik Bijeljina and FK Borac Banja Luka stand out, and he also wore the jersey of the Bosnia and Herzegovina national team. After finishing his playing career, he devoted himself to coaching, leading clubs in Bosnia and Herzegovina and the region.

‘His premature departure represents a great loss for Bosnian and Herzegovinan football.

‘The Football Association of Bosnia and Herzegovina expresses its deepest condolences to the family, friends and everyone who had the privilege of knowing and working with Mladen Zizovic.’

Zizovic had won the Bosnian Premier League when playing for Zrinjski Mostar in the 2008-09 season, while he also won the Bosnian Cup on two occasions and the Albanian Cup.

His appointment at Radnicki had followed a season in charge of Bosnian side Borac Banja Luka, before he decided to resign in the summer.

Zizovic’s side missed out on the Bosnian title by one point, while he led the club on their longest ever European campaign by guiding the team to the last-16 of the Conference League.

His former players issued an emotional joint statement following news of his death.

‘Boss, Our Žiža, We can’t believe that you left us,’ the Borac squad said.

‘We are shaken by the terrible news that reached us at Platanova 6 and we refuse to admit that we will no longer see you smiling, that we will no longer hear you making jokes at your own expense and that of others, that we will no longer listen to you talk about the football you gave your life to.

‘You left us at the age of 44, and we can only remember every moment you spent at the City Stadium. First as a player, and then as a coach who achieved the greatest European success in our history.

‘We will remember that you gave your best to Borca and Banja Luka and that together we wrote stories for eternity.

‘It’s hard to admit that you’re gone. Life is cruel and takes the best of us too soon.

‘It remains for us that you live through us and that we pass on the story of Mladen Žižović, a man, a husband, a father, a brother, a son, a coach and a football player.

His former players at Borac, who he guided to the club’s most successful European campaign last season, offered an emotional tribute on social media

‘Young man, may your glory be eternal, Banjaluka and Borac will forever remember you.’

The Serbian SuperLiga said it was ‘deeply shaken’ by Zizovic’s death and offered condolences to his family, friends and colleagues.

The league added that the match between Radnicki and Mladost is expected to be resumed at a later date. 

Radnicki are currently next scheduled to play on Saturday against FK Vojvodina.
