Former Manchester United boss Louis van Gaal has told Dutch television he has been battling prostate cancer.

The broadcaster RTL said the 70-year-old, who is currently in his third spell managing Holland, talked about his condition on its show Humberto on Sunday evening as he discussed a documentary about his life.

Van Gaal said of his players: “They don’t know. They see a blush on my cheeks and think, ‘what a healthy (person) that is’. That is of course not the case.”

He added: “I’ve been through a lot with illnesses, including with my own wife. So that’s just part of life.

“(I) as a human being have probably become richer because of all those experiences. I thought that should also be in the film.”

United posted a message of support on their Twitter feed that said: “Everybody at Manchester United is fully behind our former manager, Louis van Gaal, in his battle against cancer. Sending you strength and courage, Louis.”

Match of the Day presenter Gary Lineker tweeted: “Sending best wishes and hopes for a full recovery to Louis Van Gaal, who announced on Dutch television tonight that he’s battling prostate cancer.”

Barcelona also paid tribute to Van Gaal – who managed the club between 1997 and 2000 and again from 2002 to 2003.

“Our thoughts and prayers go out to former Barca manager Louis van Gaal, who has been diagnosed with prostate cancer,” the club said on Twitter. “Stay strong, Louis, and get well soon.”

Van Gaal managed United from 2014 to 2016, overseeing them winning the FA Cup in the final game of his tenure.

He gave Marcus Rashford his United debut and the England forward said on Monday: “Earned my debut from LVG. Will forever be indebted. You can fight this. We are all behind you.”

He had previously won league titles with Ajax, who he also guided to Champions League glory in 1995, Barcelona, AZ Alkmaar and Bayern Munich.

His third stint with Holland, which started in August last year, has included qualification for the World Cup in Qatar that gets under way in November.
