Garang Kuol, the youngest Socceroo to play at a World Cup, was stunned.
Kuol, at 18 years and 68 days, set the new age landmark when coming off the bench against France.
The Central Coast Mariners whizkid, who will join Premier League club Newcastle United in January, is renowned as the speediest Socceroo - he's 1.75m tall, or five foot seven in old speak.
And there he was on Al Janoub Stadium in Doha, trying to chase down French players.
"You can see six foot four (inches) people that are as quick as me," Kuol said of the defending champions.
"That shows you the big difference between me and some of those players and how I have got to reach that level.
"The boys were just chasing France around."
Kuol came on in the 73rd minute, just after Les Bleus scored their last goal in a 4-1 hammering of the Socceroos.
"Going into the game I was just excited to go on to the pitch," he said.
"And when the option came, I just wanted to get on the ball.
"It was a good taste to see the level that the (French) players were at, some play in the (English) Premier League and some play in the Champions League.
"We have to get ourselves to that level."
