Australia face La Tricolor in London on Wednesday morning (AEDT) at Craven Cottage after a 4-1 loss against Norway.
The Socceroos struggled to adapt to a new formation and style of football in Oslo with limited preparation time under van Marwijk.
But Luongo feels it is wrong to expect overnight success with a new head coach, and denies the national team is feeling additional pressure ahead of the Colombia game.

“That's why the Asian Cup is the best example. We got spanked a couple of times before that and then we won it and played well.
“I just think its building steps and getting things right. Yes we are going to make mistakes, but that's just part of it.”
