Watch: Beauden Barrett's try saving tackle against Los Pumas

All Black first five Beauden Barrett is often lauded for his attacking prowess, however this weekend against the Pumas he produced a fantastic cover tackle saving a certain try.

With the Pumas on the attack with 15 minutes left to play and needing a try to take the lead, Sanchez spreads the ball wide with de la Fuente and Moyano going two on one with Barrett the last man before the try line.

Barrett buys time for his cover defence to support him before tackling Moyano into touch before the winger can offload.

The tackle stopped a try that would have put Argentina into the lead and potentially have given them their first ever win over the All Blacks.

This also isn't the first time Barrett has produced a moment of brilliance on defence as he classically denied Willie Le Roux an intercept try by in 2013.
