Argentina head coach Daniel Hourcade admitted that his players' long season with the Jaguares and the national side came back to haunt them at Twickenham.
Despite having an advantage in personnel for the majority of the contest following Elliot Daly's red card Argentina couldn't get on the scoreboard until just before half-time, when Facundo Isa crossed from close-range.
Hourcade estimated that his leading players had made close to 50 trips this year, highlighting that experiencing that enormity of that new schedule had been tough on his squad.
“In part it is down to the tough season that we have had after many trips and games. For the players it was a new season," Hourcade said.
"On the other hand the team had chances in the last 20 minutes and weren’t able to score, but not because they were tired.”
Daly's early exit handed Argentina extra space to attack out wide but it was only when England had also lost Dan Cole to a yellow card before the break that los Pumas were able to exploit the leftover space, with Santiago Cordero's try after half-time closing the gap on the scoreboard to just two points.
Hourcade lamented the fact that Argentina couldn't convert a number of chances despite the extra space suiting their tactics.
“You want to take advantage of the extra man, and we made many breaks. But we didn’t score and make the most of those opportunities," he explained.
"Having an extra player gave us the possibility to open up the game and play the way we like.”
