Two Stormers players are likely to add more brawn to get the Springboks back on the winning trail in the Rugby Championship against Australia at the weekend.
Damian de Allende is expected to line-up in midfield with Jessie Kriel, while lock Pieter-Steph du Toit could add more physicality by scrumming down at flank instead of lock.
All the goodwill generated after the Boks' series victory over England in June and the drubbing of Argentina in Durban evaporated after coach Rassie Erasmus was left perplexed by a limp display in the loss against the Pumas in Mendoza.
Erasmus admitted that his side is under considerable pressure, especially since the Aussies will want to return to winning ways too after Bledisloe Cup losses against the All Blacks.
“Australia is very much, maybe in a worse position than we are with the two games they have had. They played the world champions and they gave them a proper hiding and that will make them dangerous," Erasmus told www.supersport.co.za.
"They are desperate, but we are desperate as well. We lost against a team who we didn’t want to lose against so I think it will be two teams trying their best to rectify the previous weeks’ mistakes and them playing at home will just make it tougher for us.
“We are ready and up for the challenge and we know the only way to get last week’s result out of our heads is to win.
“When you lose the pressure is more. We are here to build and everyone always says those things. We must win, that’s the end of the game.
"And if you lose there is pressure, every game you lose, it doesn’t matter when. Even if you lose against the All Blacks by one point, there will be pressure.
"The pressure is definitely on us to perform better and to win and the players understand that. I’m pretty sure the training and the effort on Saturday will show that."
