From the darkness of nearly two years of injury hell, an incandescent light is guiding Australia's Robbie Kruse towards the promised land of regeneration and reinvention.

Despite only just turning 27, the Germany-based Socceroos flier has suffered enough injuries to span an entire career and more than enough to have him questioning whether he has fallen foul of karma in a previous life.

But the fog is lifting, and in a major boost for Australia’s FIFA World Cup qualification prospects, Kruse has announced himself ready to resume his career after his latest brush with the rehab room — a calf injury which put the brakes on his season-long loan move from Bayer Leverkusen to Stuttgart before it had even got going.

A long-term knee injury, followed by a serious ankle injury suffered in January’s AFC Asian Cup final win over South Korea, have also been Kruse's crosses to bear.

But with just 35 minutes of first-team football so far this season for Stuttgart, Kruse is on course to add his guile and style to bolster the club's battle to stay in the Bundesliga with a likely return this weekend against Augsburg.

Insisting that adversity has made him mentally tougher; Kruse is bounding with the enthusiasm of a teenager at the prospect of a comeback which will have Socceroos coach Ange Postecoglou circling the dates in his diary for next March's critical qualifiers against Tajikistan and Jordan.

“It’s been a long time, obviously the last couple years at Leverkusen had been really difficult with the long-term injuries, and to miss another two months with a muscle injury has been tough,” said Kruse, with some understatement.

“It’s probably the effects of the operations I've had on my left leg ... its taken time to get my body back into a good way but I am feeling really strong now.

“I started so well early in my contract at Leverkusen and I was starting to build a big reputation there. So, to be cut down with the knee injury and then follow that up with the ankle, was pretty hard to take.

“But it’s part of football and I am working hard to overcome all the injuries … it’s made me a lot stronger mentally and hopefully I can get back to doing what I do best.”

Kruse could theoretically even been part of the camp for the clashes against Kyrgyzstan in Canberra on Thursday and in Bangladesh five days later, but it was decided not to risk him at such a crucial stage of his recovery.

"I have never doubted getting back to where I need to be, and playing the way I used," he added.

"It's also a big aim of mine to return for the national team and produce what I was [producing] a couple of years back.

"It was really disappointing to miss the World Cup ... it’s always been in my mind to go to one at least in my career and Russia is still two-and-a-half years away, but it comes around quickly.

"We have the Confederations Cup in 2017 but first we must qualify for the World Cup. I won’t be right until the next round qualifiers, which are in March.

"I am really thankful to the boss [Postecoglou] for giving me time to stay at my club and get my body in top condition, when I probably could have come to his camp, even though it wouldn’t have been beneficial to me or the national team in the long run."

After his bitter-sweet experience at Leverkusen, at Stuttgart Kruse feels he’s at the right club to complete his resurrection, even though it currently languishes third bottom of the Bundesliga.

“It’s a wonderful club. They have big ambitions to climb back up the ladder and I feel I can be a part of that," said Kruse, whose initial loan will likely morph into a permanent move if he flourishes.

He has spent long hours in the treatment room with fellow Socceroos team-mate, goalkeeper Mitch Langerak, who joined Stuttgart from Borussia Dortmund a month or so earlier but is yet to play having suffered a thigh injury during the pre-season.

“Mitch is coming along really well  ... it’s his first long injury and I've tried to help him as much as I can," said Kruse.

“He’s working really hard and will hopefully be back very soon. Everybody here knows what a wonderful keeper he is and hopefully we will soon be playing together week-in week-out, doing Australia proud.

"It would be good to see him fighting again for the No.1 spot in the national team, and proving a few people wrong, who have doubted him in the past.

"We have spent a lot of time rehabbing together. I have been in there for about two years straight now.

"It’s been difficult but it’s part of the job.”
