Samoa are desperate to finish the Rugby World Cup on a winning note.
The Manu's quarter-final hopes were ended at the weekend against Japan, a loss in which Samoa had three players sent to the sin bin and conceded a penalty try.
Assistant coach Alama Ieremia said they had no excuses and paid the price for ill discipline.
"We're pretty embarrassed with last weekend and to not qualify for the quarters is disappointing, and we certainly feel for the fans and for the country and for our families that we haven't managed to achieve that particular goal.
"It's something that we're looking to rectify this week with a performance that they can be proud of and we certainly are focused that way against Scotland.
"It's going to be a tough challenge but we certainly are pretty keen to actually finish the World Cup on a high."
Samoa are currently fourth in Pool B and need to beat Scotland and hope Japan lose to the United States to have any hope of a top three finish, which would earn them automatic qualification for the 2019 World Cup.
