Maty Ryan can easily pinpoint the big change in his life that preceded the best form of his career.
Australia's skipper and goalkeeper will kick off his record-equalling fourth World Cup campaign against Turkey in Vancouver on Saturday (Sunday AEST).
This time, the 34-year-old will have partner Chloe and son Preston, born last September, along for the ride.
The goalkeeper remembers former Socceroo James Holland telling him about teammates who took their game to another level after becoming fathers.
"Sure enough, I'm coming off probably my best season," Ryan told AAP.
Assistant coach and former skipper Mile Jedinak noticed how fatherhood has changed the goalkeeper's perspective.
Ryan is still famously professional, meticulous and routine driven - but some things go out the window when you have a baby.
