Denis Leamy believes New Zealand receive preferential treatment from referees but expects Ireland's clash with Argentina to be handled more strictly.
Referee Marius Jonker repeatedly warned the Tri-Nations champions for killing or slowing down the ball in their 38-18 victory in Dublin, but failed to produce a yellow card. Argentina can be equally disruptive but Leamy predicts they will be shown less leniency when they bring down the curtain on the autumn series at Lansdowne Road on Sunday.
"It's frustrating when you're tackled and there's a guy possibly lying there, or there's a hand holding the ball and you can't get it placed quickly enough," he said.
"Obviously everyone tries to do that, but when a ref spots something you're hoping he deals with it.
"Possibly there were times against New Zealand when there were cases for cards.
"New Zealand are very professional at slowing down the ball and stuff like that.
"Argentina will be the same, but I imagine if they infringe as much as the Kiwis did, possibly we'll see a yellow.
"You really need your referees to be strong and consistent but sometimes it's maybe one law for the rich and a different one for the poor."
