Ahead of Saturday's 'fight of the century', when Manny Pacquiao faces Floyd Mayweather in Las Vegas, Pacquiao's trainer Freddie Roach has made the startling revelation that his fighter ran away from home to live on the streets at the age of 12 - because he caught his father eating his dog.

Roach said that times were so hard for poverty-stricken Pacquiao family in the Philippines that his father cooked the dog for food. Pacquiao was so devastated by this he went to live on the streets, before turning professional just two years later aged 14.

"Manny ran away from home after his father ate his dog," veteran trainer Roach revealed.

"He lived on the street, where he bought doughnuts at a doughnut store and then sold each one for a nickel more to survive.

"He slept in a cardboard box. He fought his way through all this, turned pro at 14, and look at the man he is today.

"The Philippines is a poor place, there's no welfare, no health system and if you don't have a job or money then you do anything to survive."

The contest at the MGM Grand in Las Vegas is expected to generate more than £300m for the pair, with the split going 60/40 in Mayweather's favour.
