If South Africa and England are well acqainted in Rugby World Cups, Ireland and Argentina have even more entwined histories in this competition. If Argentina qualify in top place from the Americas qualifying group (Americas 1), they will find themselves together for the third RWC in a row.
Ireland and Americas 1 are drawn in Pool D alongside France, in what will undoubtedly be seen as the 'Group of Death'.
RWC 2003 runners up Australia are joined by Wales in Pool B whilst New Zealand are joined by Scotland in Pool C.
