Caught out.

Ireland head coach Joe Schmidt has admitted he was caught out after Argentina named lock Guido Petti in their back-row for Saturday’s at the Aviva Stadium in Dublin.

Schmidt knows Pumas head coach Mario Ledesma all too well, having coached him at Clermont when he was an assistant there. And the Ireland boss reckons Ledesma has a “cunning plan” in place for this weekend.

“There’s got to be a degree of consideration for getting the best players on the pitch, and maybe that’s what Mario’s looking for, with Guido Petti in the back row, with [Matias] Alemanno and [Tomas] Lavanini at lock this weekend,” Schmidt told Sky Sports.

“It’s probably not a change-up that we foresaw but at the same time I’m sure there will be some sense to it.”

“Knowing Mario there will be some cunning plan to it, and we’ll have to probably decipher it on the run, once we’ve kicked off on Saturday.”

Roll on Saturday.
