The Matildas have collected precious new information that will pay rich dividends at next year's World Cup, coach Joe Montemurro says.
Montemurro and his charges are wiser and more worldly after gathering vital intelligence during the Matildas' two friendlies against Mexico.
The Australians made amends for a 1-0 loss in game one with a dynamic 3-1 victory in Sydney on Tuesday night.
That result, after strikes from Caitlin Foord, Alanna Kennedy and an own goal, pleased Montemurro - but not as much as the lessons learnt.
"There's a lot of positive signs but we know we have to clean things up," he told host broadcaster Paramount.
"And these games are perfect for us.
"Now we have got all this information in regards to these type of teams and now we know how to deal with them."
