MELBOURNE (Reuters) - World Cup winner and Tonga coach Toutai Kefu said he and his family were grateful to be alive after they returned home from hospital on Friday following treatment for serious injuries sustained in an attack by intruders.

The 47-year-old, who played 60 tests for the Wallabies around the turn of the century, wiped away tears as he revealed details of the home invasion by knife-wielding teenagers in the early hours of Monday morning.
