Two late goals allowed France to edge past Nigeria in the last 16, but Cabaye insists that relaxing is not an option for the squad.
"There is still far to go. We have to enjoy it," the Paris Saint-Germain midfielder is quoted as saying by The Guardian. "We can say we are in the last eight and that is good, but we have to stay humble and not arrogant.
"If we start to play more easier and relaxed we are going to be getting back to France straight away. So we are confident but focused and we want to stay for as long as possible in Brazil."
Germany reached the quarter-finals thanks to a dramatic 2-1 win over Algeria in extra time on Monday.
