Ryan has played just 10 LaLiga matches for 15th-placed Valencia - only two this season - as he continues to play second fiddle to Diego Alves while also competing against a third quality gloveman in Jaume Domenech.

Adding to his angst is the instability that has reigned at the former LaLiga high-flyers since he joined them from Club Brugge on a six-year deal in July 2015.

Since that time the club has had five different coaches.

The latest, former Italy coach Cesare Prandelli, acknowledged to the players he had inherited a less-than-ideal situation last month.

The 24-year-old Ryan is anxious to play regularly, acutely aware he's still yet to hit his prime and that his main rival for the Socceroos No.1 jersey, Mitch Langerak, is getting regular game time for 2. Bundesliga side VfB Stuttgart.

Ryan said if nothing changes he may be forced to start looking elsewhere.

"It's still a long way away," Ryan said in Bangkok, where the Australian team are midway through a 10-day training camp.

"But obviously common sense will tell you that with the situation like it is at my club, if I'm not getting the desired game time then I'll be looking at my options.

"That's all I have to say about that at the moment.

"Football is like life - a lot can happen between now and January when that window opens."

Ryan, who is almost certain to start against Thailand, admitted he probably wouldn't really appreciate what he's learnt from the toughest period of his career until further down the track.

"I knew going to a club like that, that competition for places was going to be tough, but knowing it and living it are two different things," he said.

"Having what it might be in your head to the reality, I've witnessed that first hand and you've just got to not take it for granted.

"Any opportunity you get to play you have to make the most of it.

"One bad day at the office can be the difference, a change in manager can be the difference - any tiny thing can be the difference.

"I just have to appreciate the privilege I have at a big club like Valencia instead of having a negative-minded approach to it in terms of not being happy because I'm not playing."
