Cristiano Ronaldo breaks down in tears during an interview with Piers Morgan which will be broadcast on British television this week.The 34-year-old, who is widely considered to be one of the greatest footballers of all time, was shown a video of his late father talking about him.Jose Dinis Aveiro died of liver failure in September 2005 at the age of 52 following a battle with alcoholism.Ronaldo was just 20 years old at the time and still in the process of developing into a top player under Sir Alex Ferguson at Manchester United.Ferguson allowed Ronaldo to miss a Champions League match in order to be with his dying father in a London hospital - a compassionate gesture the Portuguese superstar has always been immensely grateful for.

Morgan and the ITV team unearthed some old footage of Ronaldo’s father praising his son while stood on his doorstep. Cristiano had never seen this video before and it brought him to tears.

"I never saw the video. I never saw that video. Unbelievable,” Ronaldo, wiping away the tears, tells Morgan.

Asked by Morgan what it was that made him so upset, Ronaldo replied: “To be the number one and he doesn’t see anything. He doesn’t see me receive awards.”

Morgan then adds: “He never saw how great you became…”

“Never,” Ronaldo responds.

"My family see, my mum, my brothers, even my old son, but my father, he didn't see nothing, and it was... he died young."

It’s rare to see such raw emotion from Ronaldo.

He may seem like a superhero but, at the end of the day, he’s only human.

"I think the interview would be funny, but I didn't expect to cry,” Ronaldo added, per the Mirror. “But I never saw these images. I don't know where you... I have to have these images to show my family.

"But I really don't know my father 100 per cent. He was a drunk person. I never spoke with him, like a normal conversation. It was hard."

The rest of Ronaldo’s interview will be shown on Tuesday night at 9pm on ITV.
