Bradley Lowery's parents have confirmed the six-year-old has died following a long battle with neuroblastoma -- a rare type of cancer.
Sunderland supporter Lowery came to the attention of many football fans because of his friendship with former Black Cats striker Jermain Defoe.
He went on to become a mascot for Sunderland in the Premier League and England in a World Cup qualifying game against Lithuania and found a place in the hearts of thousands of football fans around the world with supporters of different clubs making banners and chanting his name at matches.
