Johnson’s men crashed out in the quarter-finals, equalling their worst ever campaign, and were dogged by off-field controversy.
That has led to questions about the future of Johnson, who also stands accused of failing to find the right system to get the most out of his players.
But Cueto said: “No-one cares about how you’re playing if you’re getting results. The result is the priority, the performance is No2.
“That’s rugby though, that’s the way it always has been and that’s the way it always will be.”
Former England captain Will Carling has tipped Johnson to walk away, rather than attempt to lead the squad into a home World Cup in 2015. “I don’t know if Johnson will put himself up again,” he said.
“He’s a very loyal man and if he is told the coaching team needs to change, would he hang around? I don’t know.”
