Manchester: Australia coach Justin Langer believes Steven Smith and David Warner will be under no extra pressure when they face South Africa for the first time since both batsmen were given 12-month bans for ball tampering.

Then-captain Smith and Warner, his deputy, were hit with year-long bans by Cricket Australia for their roles in an extraordinary incident during a Test in Cape Town that saw teammate Cameron Bancroft indulge in a brazen breach of the rules by applying sandpaper to the ball.
