Lomu is determined to play again for the All Blacks Feature: What now for Lomu?

All Black legend Zinzan Brooke has advised Jonah Lomu to forget about playing in this year's World Cup and concentrate on his health problems.

Lomu suffers from Nephrotic Syndrome, a kidney problem which now requires dialysis treatment three times a week.

The 28-year-old has vowed to return to health and fitness in time to make the New Zealand squad for the tournament which starts in October.

But Brooke - who played in the 1995 World Cup alongside Lomu - told BBC Sport that the 28-year-old's place in the history of the sport is assured and that he has no need to push himself.

"I don't think Jonah should even be thinking about making the World Cup - that shouldn't be his priority," Brooke told this website.

I am desperate to get back into the Wellington team Jonah Lomu

"From what I know about his health problems, my advice would be that Jonah should just look after himself.

"He doesn't have to prove anything to anyone, he's done it in two World Cups and he's going to go down as one of the all-time greats of New Zealand and world rugby.

"If he concentrates on his health, then he might get in for the World Cup, but his health is the most important thing."

On his official website, Lomu said that he felt "good" after a month of dialysis and that he was hoping to return to action with his club side.

"I feel stronger now than I did in the last World Cup," he said.

"I am back training when I am not dialysing and when [his club side] the Wellington Lions get back to training, I will be with them.

"My intention is to make myself available for selection into the Lions team for the NPC.

"At this stage I am still living in Auckland because my doctor and specialist are there but I am desperate to get back into the Wellington team."
