Earlier this week it was reported the 23-year-old defender, who has started five of the past seven games for the Australian national team, had been informed by the struggling J-League club he wasn't wanted for next season.

However, Spiranovic told goal.com the report was 'unnecessary speculation' and insisted he was a required player at Urawa for 2012.

"I have a contract for next season and what I hear from the club is all positive, so that was definitely a case of unnecessary speculation," Spiranovic said.

The report claimed Spiranovic was worried about his Socceroos chances due to his lack of game time after falling out of favour late in the season under interim Urawa coach Takafumi Hori, who took over following the dismissal of Zeljko Petrovic in October.

Spiranovic admitted that the situation under Hori was frustrating but said he was confident he'd have a chance to win back his place under a new coach next campaign.

"This season the club actually had offers from three different European clubs for me and turned them down. I think that sends a message, for me anyway," Spiranovic said.

"What's happening at the club, there will be changes next season, so with a new coach everyone starts off at the same level and it's up to me to make sure I'm playing next season.

"There was a situation maybe five games ago when the new coach came in and I was away with the national team.

"[Hori] came from the youth team and didn't have a lot of experience and he just went with the boys who he knew. He coached a lot of the boys at youth level and actually played with a lot of the older boys.

"I'm not sure if the language barrier played a part, but that's what he went for. But we managed to stay in J1."

Urawa had a 2011 to forget, narrowly avoiding relegation and Spiranovic said there were a variety of factors behind their poor campaign,despite retaining their mantle as Japan's best supported club.

"There were a number of issues, obviously a change of coach. From the start it was always going to take time to adapt with a new system, new formation," he said.

"Also there were a lot of new players who came in, a lot of senior players moved on to other clubs. That whole process took a few months.

"Once you're fighting down the bottom and you get a bit of bad luck it's very difficult. At the end of the season, the boys showed a lot of character and fought it out, credit to us, we can look forward to another season in J1."

As for the interest from abroad, Spiranovic insisted he's content in Japan for now but admitted he'd love to return to Europe one day, having previously spent four years in Germany with Nurnberg.

He added: "Definitely in the future I see myself going back overseas, but it's just a matter of timing and going to the right club."
