Immanuel Feyi-Waboso has seven tries in 13 caps for England

Nobody was pretending that England don't have room for improvement.

With the players out on their feet, the Twickenham air still humming with tension, Argentina aggrieved and the England bench relieved, they couldn't.

The skinny look to the scoreboard - a 27-23 victory - matched with frayed nerves and chewed fingernails.

England's attack was aimless, bordering on the clueless, on occasions. Fourteen penalties conceded was plenty too many. Thirteen unanswered Pumas points at the start of the second half was a worrying loss of control. The defence flagged alarmingly late on, losing speed and structure as Argentina scored a last-minute try and came within metres of a last-play clincher.
