Jamie Maclaren's swift adjustment from Dubai holidaymaker to the Caltex Socceroos' last-chance saloon convinced Bert van Marwijk to include him in a beefed-up attacking arsenal.
The 24-year-old striker was on Sunday (AEST) named in Australia's final 23 for this month's FIFA World Cup, just seven days after arriving as a latecomer to the pre-tournament camp in Antalya, Turkey.
His hopes looked over when he was excluded from the preliminary 26-man group selected in May, but a brief injury concern over Tomi Juric opened the door to a recall and Maclaren made the most of the opportunity.
"He came in and I'm satisfied about him. He's a typical player who always gets a chance [to score]," van Marwijk told reporters.
"It's difficult for him because he was already on vacation for eight or nine days.
"I wanted to give him a real chance, a week. He had to train very hard from the first moment.
"We train very intensively and [often] two times a day. It was really difficult for him, not really fair for him.
"But he made a good impression. I think I need him."
Maclaren's inclusion alongside exciting Melbourne City winger Daniel Arzani heralded a concerted move to expand the squad's options in the front third.
Van Marwijk cited the emergence of Western Sydney Wanderers right-back Josh Risdon, who impressed in the 4-0 friendly victory over the Czech Republic, as giving him the confidence to redistribute resources.

"[What is] very positive is the development of Josh Risdon," the Dutchman said. "I have another two players in the squad who can play that position.
"We have enough central defenders and the defensive midfield players are the same.
"And now I have options in front with several types of centre-forwards, number nines.
"Andrew Nabbout can also play on the side and the number 10 position. I have more players who can play in more positions."
