Warren Gatland’s went into the tournament with expectation low and fears they could potentially fail to make it out of the group-stage, but Wales made it through with a perfect record to top Pool C, picking up a record win over Australia in the procees.
They reached the semi-finals of the 2011 and 2019 World Cups, and are a win over Argentina away from adding another last-four appearance to the list.
The Pumas fell to an opening defeat against England and have not been particularly convincing, but came through a winner-takes-all clash with Japan to book their place in the quarter-finals.
The winner of this last-eight clash will go into the semi-finals as underdogs, with Ireland or New Zealand waiting for them in Paris.
