Langer warns Aussies to beware of Proteas in Caribbean tri-series

Acting Australian head coach Justin Langer has called on his side not to take South Africa lightly in the ongoing Caribbean tri-series, saying the AB de Villiers' side look really good on paper.

Langer's comments came ahead of their second clash against South Africa at the Providence Stadium in Guyana.

The Proteas started their series with a four-wicket defeat against hosts West Indies while Australia opened their campaign by comfortably beating the Caribbean side by six wickets.

Langer, however, said that South Africa are brilliant runners, insisting they would surely run hard and field well in their upcoming crucial match, Sport24 reported.

The 45-year-old believes the Proteas would be fully geared up to run his side ragged in the field and, therefore, called on the Steve Smith-led side to remain at their absolute best in order to outclass them.
