Bosnich: Ryan can be Australia's best ever
Ryan made a big leap in the off-season when he moved from Club Brugge in Belgium to La Liga giants Valencia in Spain.
The goalkeeper helped Valencia reach the Champions League last week and is set to fly into Australia for the upcoming World Cup qualifiers.
Ryan has impressed since joining Nuno Espirito Santo's side and Bosnich believes he can become the best ever goalkeeper to represent Australia.
"He can become the best keeper in Australian history, better than anyone of us," Bosnich explained to the Sunday Herald Sun.
“At 23, he’s already played in a World Cup. But more importantly, he’s playing at an even higher level and that’s the Champions League.
“It’s the best of the best, regardless of where you’re born. He’s right on course. He won keeper of year in Belgium and now he’s arguably in the best league in the world.
“At comparative ages, Mat is well ahead of any of us.”
The ability for Ryan to compete in the Champions League against the world's best, as well as a number of big names in La Liga, Bosnich believes he will always continue to improve as a goalkeeper.
“With the ball at his feet I can’t think of anyone that’s better than him around the world. He’s as good as [German ‘keeper Manuel] Neuer. It’s like having extra outfield player,” Bosnich said.
“With shot stopping, some keepers make saves that turn games and he’s one of those. We saw it against Monaco in both legs, especially the first.
“Another reason is he’s playing in one of the best leagues in the world. And against the best players, you’re only going to get better.
“Everyone’s got things they can work on. One thing that will come with experience is his decision making. That will lead to an ability to dominate the box.
“Once he gets that up there in the other levels, he can be as good as anyone in the world. He’s just got to keep playing at the highest level and stay in the side.
"Mentally, he’ll develop naturally.”
