'You know nothing about scrums!' Pumas coach takes cheeky shot at 1 NEWS journo

1 NEWS sports reporter Dewi Preece last night earned the ire of Argentinian coach Mario Ledesma, after questioning the legitimacy of the Pumas scrum.

But having spent his entire playing career as a centre, Ledesma joked that Dewi's knowledge of the scrum was insufficient, earning a laugh from the gathered media.

"What position do you play?" Ledesma asked, during last night's media conference.

"Thirteen (centre), a small 13," Dewi replies.

"Ah, so you know nothing about scrums," a grinning Ledesma responded, before moving on, avoiding answering Preece's question about the strength of the Pumas' scrum which found itself under huge pressure from the All Blacks all night, during their 46-24 defeat.
