A former Manchester United manager has confirmed on live television that he is battling an "aggressive form" of cancer.
Current Netherlands boss Louis van Gaal recently took to Dutch TV programme Humberto to promote his new film, LOUIS.
However, the veteran manager shocked the football world durig the broadcast when he revealed he has prostate cancer, with his journey in this battle against the illness featured in the documentary.
This came as a surprise to many, including the players in the Dutch national team, as the head coach had kept his diagnosis a secret from them.
He explained that, while he has already started treatment, he decided not to tell his squad so they could concentrate solely on their friendlies and 2022 FIFA World Cup qualifiers.
"In each period during my time as manager of the national team, I had to leave in the night to go to the hospital without the players finding it out until now," the 70-year-old revealed during the show, per Voetbal International.
"While thinking I was healthy. But... I am not.
"I think you don't tell people you work with like that because it might influence their choices, their decisiveness.
"So I thought they shouldn't know. You don't die from prostate cancer, at least not in 90% of the cases.
"It is usually other underlying diseases that kill you.
"But I had a pretty aggressive form, got irradiated 25 times. Then you have a lot of management to do in order to go through life.
"I did have preferential treatment in the hospital.
"I was allowed in through the back door when I went to an appointment and was immediately pushed into another room.
"I have been treated wonderfully. You will, of course, tell your friends and relatives about it.
"The fact that nothing has come out yet also says something about my environment. That's great."
