Wales' James Hook has revealed that he has "unfinished business" at the World Cup after the heartbreak he suffered in New Zealand four years ago.
The 30-year-old was part of the Wales side that was knocked out at the semi-final stage by France, and he has made only four starts for his country since.
"I was hoping to be involved in this World Cup and get out to do something. Hopefully, I will have the opportunity to do that and play a positive part," Hook told reporters.
"There have been a few times when I've thought Test rugby has gone away from me, but when I am with Gloucester, it's about working hard for when there is hopefully an opportunity.
"We've had some pretty major injuries which have opened the door to me, but now I am here, it's about getting out there, enjoying it and giving my best. Yes, there is unfinished business."
Hook was called up as a replacement for Wales last week as a result of their injury woes, and he could be in line to win his 80th cap against Australia on Saturday as the two sides battle it out to see who tops Pool A.
