Stubbins has been strongly linked to the new Northern Queensland A-League club and could be on the move within months if he's awarded the senior coaching position.

It would leave a big gap in Aurelio Vidmar's support crew and his brother could prove the perfect fit.

Tony, who recently joined the Reds to assist Joe Mullen with the club's Youth League side, said he'd be concentrating on his assigned role despite the possible departure of Stubbins.

"I don't look that forward, one day at a time here," Vidmar said.

"I've been brought here to work with Joey Mullen and I've only been in a coaching role for three days so I've got to learn this position, I've got to learn the players here and I can definitely offer experience."

"At the moment with the youth players is ideal and down the years you look further. At the moment it's one step at a time, I don’t want to jump the gun and just enjoy what I'm going to do."

Vidmar, who played with the Central Coast Mariners last season, also ruled out pulling on the boots for an encore performance with the Reds.

"It's done and dusted, it's the next phase of my career. I had a fantastic career and I'll see how I go as a coach," he said.

The former Socceroo said he was looking forward to working with United's youth team which he believes will benefit both the A-League and Australia's emerging players.

"Now this is their opportunity to get into a professional environment and who knows, the next few years there could be players that come through the youth team," he said.

"Australia, for so many years, has produced a lot of good players and unfortunately some have gone overseas at a young age and have not really developed."

"So hopefully we can keep them here as long as we can and give them a good base so when they do pursue a career overseas that they have a solid grounding."

"We've lost a lot of young players overseas to clubs and we don't know where they are."

Vidmar said he may also be called upon to help with the senior side. But at the moment he's happy with how the South Australian team has been performing.

"The defence has been good so I don't think we need to touch anything. (But) during the course of the season defenders can get into sloppy or bad habits and that's something we look at and rectify," he said.
