Springbok flanker Francois Louw said his side have put their loss to Japan behind them and are still focused on winning the Rugby World Cup.
Louw admitted that the defeat was a huge disappointment but revealed that it has united the Springbok squad and there is still a positive attitude in their camp.
“Our backs are against the wall right now,” he said.
“We have three tough games ahead of us. We are not going to underestimate any team in the World Cup. I don’t think we ever did.
“Losing a game doesn’t mean you are down and out. There are six games left all the way to the final.
"We’ll take each game as it comes and this week our focus is on Samoa.”
When asked if the Boks can still win the World Cup, Louw replied: “I think we are in a position where we have to feel confident about that (winning the World Cup).
“We need to pull together. We know what needs to be done. I believe we have the ability to pull back together, to pull tight, to look forward and deflect any negativity.
“We’ve hit a bit of a stumbling block. It’s time to regroup and pull together in a positive way. Our focus is to climb the pool and finish top.
“It’s still in our hands, still in our grasp to go through the pool games and qualify for the play-offs.
“You want to finish top of your pool to get a better draw in the play-offs.”
Louw said South Africa are determined to restore their pride by beating Samoa in Birmingham on Saturday.
“We know we can produce," added the Bath stalwart.
"We know the brand of rugby we can play. We can beat any side in the world.
“We need to win every single game now. It has not been a great moment for South Africa and South African rugby history.
"It is what it is and we have to face up to reality and turn it around.”
