Samoa Under 20s rugby coach Lemalu Semo Sititi is urging his team to show better discipline in their final Junior World Championship clash against South Africa.
The Samoans lost their first match against New Zealand but beat Scotland on Friday, despite having two players sent to the sin bin.
Sititi is expecting a bruising, physical encounter against the Baby Boks, who are unbeaten after a stunning upset win over New Zealand.
"We have to lift up our performance based on our last game against Scotland. South Africa are massive, they're big, they're a well-drilled team but we have to prepare for that. Discipline was a massive part and I've expressed to the boys that I hate that. I don't want any sin bins or any yellow cards or anything like that but the confidence we've got at the moment it will give us a good game Tuesday."
Sititi says Samoa are currently ranked eight overall and want to improve on last year's ninth place finish.
Fiji take on Ireland in their final pool match today, still searching for their first win of the tournament.
