Walsh said unlike the Glasgow Commonwealth Games, the Sardar Singh-led side has the ability to turn the 2010 Guangzhou bronze into a gold at the Asian Games to be held from September 19 to October 4.
"One of the really important area is self belief. That's very closely linked with confidence and the willingness and ability to play the level without the fear of losing," Walsh told PTI ahead of the team's departure for Incheon later tonight.
"The problem was that the players had no belief that they could win the gold (at the Commonwealth Games). It's a process of development, it doesn't happen overnight. But I think these group of players sincerely believe that if they play to their potential they can beat against Malaysia, Korea, China, Pakistan, Japan and win the title," the Australian said.
Insisting that India and Korea are the teams to beat in the Asian Games, Walsh said they have improved upon their defensive skills post the World Cup earlier this year.
"You got to understand what you are trying to do and believe in your abilities. I think we are growing and leaning those things," he said.
