Nigel Carolan braces Ireland for bruising Pumas encounter in World Cup opener

Nigel Carolan may be in charge of the Irish U20s at a world championship for the first time but the Galwayman has been involved with enough underage national sides to know they face a tough test against Argentina today, 3.30pm (live on TG4).

Ireland will open their World Rugby U20 Championship in Parma today against an Argentinian side who will be bidding to maintain the good record they hold against the Irish at this level.

And Carolan, backs coach in Argentina when thethen hosts turned Ireland over 24-21 in 2010, said that they will again be formidable opponents.
