Middlesbrough midfielder Rhys Williams admits he is slightly worried about a nagging pelvic injury that has troubled during the past 12 or so months.
The 23-year old, who is in Brisbane preparing with the Australian team for Friday's opening World Cup qualifier against Thailand, told The World Game that he continues to put all of his focus on the problem and has fears that it could come back to strike him down at any time.
"I've still got to work on my injury every day for the rest of my career," said Williams, who was forced out of the 2010 World Cup because of the injury.
"Because there is always the chance it can come back if I'm lazy or doing too much.
"I'm not quite over it yet and I don't think I will be for a good while.
"Playing wise and training wise it's feeling good.
"But mentally, every little pain I get around the area I go "oh s---, what's going to happen now, am I going to be out for another year?
"So it's all about working hard every day and doing little bits and pieces to try to make sure it does not come back again.
"Sometimes I feel like I'm treading on eggshells.
"If I feel a little niggle or anything I start asking myself 'have I done enough work this week?'
"But I've played six games in the last three weeks and I got through them with flying colours.
"So, touch wood, I'm not far off from saying to myself 'I'm feeling good and fresh'."
Williams has started all five Championship matches for Boro so far this season as the Teessiders sit fourth following an undefeated beginning.
