Former professional soccer player and coach Sinisa Mihajlovic is dead. The Serb died of leukemia at the age of just 53, his family announced on Friday.

In a statement from the relatives, which Italian media such as the news agencies Ansa and Adnkronos circulated, he was described as a "unique man and an exceptional professional".

His death was also called "unjust and premature".

The former midfielder belonged to a golden generation of footballers from the former Yugoslavia in the early 1990s.

Mihajlovic was diagnosed with blood cancer in 2019.

After a bone marrow transplant and three chemotherapies, the former Yugoslav international returned to the coaching bench at FC Bologna in Italy's Serie A, where he spent most of his professional career as a player.

In March of this year he had to be treated again.

After a disappointing start to the season, the club parted ways with Mihajlovic, who then did not take on a new engagement with another club.

"He fought bravely against this terrible disease," the family statement said.

A few days ago his condition had deteriorated and he had to be admitted to a Roman clinic.

The death of the athlete caused grief in Italy.

"You fought like a lion on the pitch and in life," wrote Prime Minister Giorgia Meloni on Twitter.

"You are and will always be a winner." Other top politicians, athletes and officials also expressed their condolences, and FC Bologna tweeted: "Addio Mister, you will live in our hearts forever."

“Serie A mourns Sinisa Mihajlovic, a football icon.

His talent as a footballer and coach, his strength and his humanity are examples of an unforgettable mark in Italian and world football," wrote Serie A President Lorenzo Casini.

Lazio Rome and Italy's national coach Roberto Mancini, who had played with the Serb at Sampdoria Calcio, also offered their condolences to the family.

Mihajlovic celebrated his greatest club success early in his career by winning the 1991 European Cup with Red Star Belgrade.

A year later he moved to Serie A, where he played for AS Roma, Sampdoria Genoa, Lazio Roma and Inter Milan.

He was always seen as a physical and rough opponent, and he was also a very dangerous free-kick taker.

In those years he won, among other things, the European Cup Winners' Cup with Lazio in 1999 and was champion with the capitals (2000) and Inter (2006).

After that season he ended his active career.

He became a coach and looked after AC Fiorentina, Sampdoria Genoa, AC Milan, Sporting Lisbon in Portugal and, until a few months ago, Bologna.

From 2012 to 2013 he was national coach of Serbia, but failed to qualify for the World Cup in Brazil with the team.
