Luke Benedict, of the Daily Mail, looks at Jonny Wilkinson's latest revelations from his new autobiography.
"Jonny Wilkinson has revealed that his infamous fear of failure and obsession with perfection made him so depressed he harmed himself.
The England fly-half was so distressed by a seemingly endless succession of injuries that he was driven to biting his own hand, screaming under water, sleep-deprivation and ripping up his clothes.
The 32-year-old documents his decline into dark obsession in his new autobiography, Jonny.
It began in the summer of 2002 when he agreed with Clive Woodward, then the England coach, to miss the tour to Argentina and rest after five years of summer touring."
