Simon Webster believes Scotland's forwards must outwit rather than outmuscle their Argentina counterparts if they are to square their two-Test series this weekend.

The home side's superiority at the breakdown helped them turn a five-point deficit into a 21-15 victory in Saturday's first Test in Rosario.

Winger Webster, who began that match as a replacement and picked up his 34th cap when he came on with nine minutes to go, is confident the tourists can nullify this advantage by keeping the ball alive and playing to their own strengths in Buenos Aires.

"The Argentinian team is very difficult to play against because they are so good at the contact area," he said.

"That makes it quite hard to get rhythm to our attack and that was the case, their strength at the breakdown 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."

Frank Hadden's men go into the match with three of their injured players aiming to be in contention.

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 on Tuesday as Hadden fielded two 15-man sides at the GEBA club ahead of the second Test at Velez Sarsfield's home ground.

As well as winning the forward battle, Webster believes Scotland must lower their error count this weekend.

"I think that international games are quite often decided over very small things and these very small things basically turn the game over," the 27-year-old said.

"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.

"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."
