Scotland winger Simon Webster is confident the tourists will deliver the improved performance needed in the second Test against Argentina after they suffered a 21-15 defeat in Rosario.
Frank Hadden's men go into the second Test in Buenos Aires with three of their injured players aiming to be in contention for the game on Saturday.
Wing Simon Danielli (swollen knee), fly-half Dan Parks (ankle) and lock Scott MacLeod (thigh) have all been receiving treatment following the first Test defeat.
All three trained with the squad today as Hadden fielded two 15-man sides at the GEBA club ahead of the second Test at Velez Sarsfield's home ground.
Webster believes solving small problems encountered in Rosario could lead to a better result in Buenos Aires.
He said: "I think that international games are quite often decided over very small things and these very small things basically turn the game over.
"We were five points ahead and after a couple of penalties all of the sudden Argentina were in the lead.
"It is very different to being 15-10 in the lead and then being 16-15 behind as we had to change our way of playing.
"We have a good chance of winning if we can eradicate the silly mistakes we did. We watched the match and we realised that if we correct simple things that went wrong then we have a real opportunity to win," Webster told PA Sport.
"We made some errors with several passes and some guys were in the wrong places.
"These little things put pressure on us and take the pressure off of Argentina. If we can change that I think we could win "
The 27-year-old Edinburgh man began last Saturday's clash as a replacement and picked up his 34th cap when he replaced debutant Thom Evans with nine minutes to go.
Webster believes that the key to success on Saturday will be stopping the Pumas at the break down.
"There were parts (of last game) where we were really good and others quite poor, but we are trying to build on the good things we did and trying to eradicate the bad things.
"The Argentinian team is very difficult to play against because they are so good at the contact area. That makes it quite hard to get rhythm to our attack and that was the case, their strength at the break down made it hard for us the whole match.
"There isn't much to do to avoid that. They know that they are really good at it so they take advantage of that.
"The only thing is to keep the ball alive and find the way to attack, playing our rugby," added Webster.
England Under-18 head coach John Fletcher insists his young side will be better for the experience after beating Italy in the bronze final to round out their 2015 Rugby Europe U18 Championship campaign in style.
