Argentina flanker Juan Manuel Leguizamón has admitted that starting the year against the other Rugby Championship sides has not been easy.
Los Pumas have suffered defeats to New Zealand and Australia in their first two Tests of the year.
Next they face South Africa in Durban seeking a first win in the competition but Leguizamón admits that Argentina have plenty of work to do.
The veteran though still believes that Argentina can deliver with more investment in their own game and by backing up their hard work in training this week.
"We have to improve our game in order to progress, and we had some positive things [against Australia] but only to a certain point," said Leguizamón.
"In attack we have rarely prospered and we need to impose our game plan, attack and have the ball, and build on what we've worked on this week.
"It's only our third game of the year together as a group and we have to start by facing the three best sides in the world, and that's not easy.
"We must also put that aside and focus solely on us and start producing with our game plan."
