Argentina head coach Mario Ledesma was annoyed that his team failed to take advantage of an under par New Zealand display on Saturday.
The All Blacks came away with a 35-17 victory to secure another Rugby Championship title and condemn the hosts to a third defeat in the competition.
Los Pumas have improved under the guidance of Ledesma and were impressive in overcoming South Africa and Australia recently, but their boss was unhappy by their efforts in Buenos Aires.
“They weren’t the normal All Blacks that we were playing tonight,” he said. “I don’t think they were that clinical but we couldn’t deliver; we underperformed in terms of delivery from scrum and lineout. In your (All Black) scrums we got dominated and we couldn’t do the simple things right.
“We had a lot of missed opportunities from scrum and lineout and even simple breaks. I think we had as many breaks as they did but we couldn’t score.
“The only thing I wanted to see from the boys was ourselves and I couldn’t see it.”
Meanwhile, All Blacks head coach Steve Hansen was content with their performance but admitted that improvements still need to be made.
The defending world champions were stunned by South Africa two weeks ago and, although they displayed developments from that display, Hansen insisted that it was nowhere near perfect.
“We were better. But you don’t go from naught to 100 straight away,” he said. “There will be some more learnings for us but, when you look at who was out there on the park at the end, it was a pretty young group, so you have to be really pleased with how they coped with some of the pressure.
“I thought our kicking was better tonight, maybe not as accurate as we would like, but we kicked to the right places, and at the right times, a lot more than we did a couple of weeks ago.
“At times we played some good footy and at other times we didn’t play that great. But you’ve got to give a wee bit of credit to Argentina, too, they’re a very difficult side to play against, particularly here.”
