A statement shared by Raiola’s family on his Twitter account read: “In infinite sorrow we share the passing of the most caring and amazing football agent that ever was.
“Mino fought until the end with the same strength he put on negotiation tables to defend our players. As usual, Mino made us proud and never realised it.
“Mino touched so many lives through his work and wrote a new chapter in the history of modern football. His presence will forever be missed. Mino’s mission of making football a better place for players will continue with the same passion.
“We thank everybody for the huge amount of support received during these difficult times and ask for respect to the privacy of family and friends in this moment of grief.”
Raiola’s account tweeted in January to say he was undergoing “ordinary” medical checks and that he had not required “emergency intervention”.
The confirmation from Raiola’s family came two days after incorrect reports of his death spread. Alberto Zangrillo, head of the anaesthesia and intensive care unit of San Raffaele hospital in Milan, where Raiola was being treated, said: “I am outraged by the phone calls from pseudo-journalists who speculate on the life of a man who is fighting.”
Raiola rose to prominence in the Netherlands and Italy in the 1990s and was involved in the deals that saw Dennis Bergkamp and Pavel Nedved move to Serie A.
More recently, Raiola helped to broker Paul Pogba’s then-world record transfer to Manchester United from Juventus, as well as Erling Haaland’s move from Red Bull Salzburg to Borussia Dortmund.
