Springbok hooker Bongi Mbonambi has warned that the Boks must not be complacent about their clash against Argentina in London tomorrow afternoon. According to Mbonambi: "They’ll be hurting after last week, so we have a big challenge ahead, but we’ve done our homework, and our preparation has been going well. That said, it’s definitely going to be an arm-wrestle of a match. We expect a proper retaliation from them on Saturday."
