Sam Burgess says personal reasons and his undying love for rugby league led to his return from rugby union.
The dual England international is heading back the NRL with South Sydney after 12 months in the rival code culminating in a controversial Rugby World Cup campaign for his country.
"My decision to leave Bath and move back to Australia was for personal reasons, but it was also because I wanted to spend the rest of my career playing the game that's in my heart," said Burgess in a newspaper column for England's Daily Mail.
"Rugby league is in my heart. I'm looking forward to getting back to Sydney, where I'll be with my family and playing for the Rabbitohs alongside my brothers again."
