Albion keeper Mathew Ryan believes he has learnt from his painful experiences in the last World Cup in Brazil as he tries to avoid more early knockout heartache with Australia against Denmark.

Defeat for the Socceroos in Samara tomorrow (1pm), combined with a win or draw for France against Peru, will end the Aussies' hopes of progressing from the group stages to the last 16 for only the second time.

A point or more will keep their chances alive, with goal difference and then goals scored the decisive factors if countries finish level on points.

Ryan (below) made his World Cup debut in Brazil four years ago, when he conceded three goals in each of Australia's group defeats by Chile, Holland and Spain.

The Argus: He allowed a long-range effort from Memphis Depay to swerve past him for Holland's winner.

Ryan said: "It was my first taste of football at the highest level and I think I was a bit raw.

"At the time I wanted to be as ready as I could be but, looking back now, and what I've experienced since then, four years ago I was a younger and less experienced goalkeeper.

"It was the biggest learning curve in my career until now. The error in the Holland game was a difficult one to take.

"It was more in my approach to the games that I made probably the biggest error of all in thinking I needed to raise my game to another level in order to be successful.

"I should have just gone there and played my natural game, which enabled me to get in that position in the first place. I was just a bit in awe of the enormity of the tournament and who we were facing and focused a little bit too much on that side of things.

"This year in the Premier League, the more practise you get at something, playing at a level, the speed, the physicality, the intensity week in week out, you get more used to it, you adapt."

Ryan maintained his accomplished form for Albion in Australia's opening defeat by France.

He will be trying to add to the Socceroos' only clean sheet in World Cup history - against Chile in 1974 - in the clash with the Danes as Australia attempt to emulate their knockout-reaching heroes of 2006.

The Argus: Colombian winger Jose Izquierdo and Nigerian defender Leon Balogun (above), Albion's other World Cup participants, could have busy summers again next year.

Colombia will be involved in the Copa America in Brazil and Nigeria in the Africa Cup of Nations in Cameroon. Both tournaments take place in June.
