Stuart Lancaster happy with England's defence and accuracy
Stuart Lancaster was pleased with the margin of England's victory over Argentina in the first Test in Salta, but says his team must improve their discipline after giving away a 15-5 penalty count against the Pumas.
The tourists defeated the home side 32-3 in the first Test and ran in four tries, including one from debutant Billy Vunipola.
The England head coach was pleased with the first-half performance but admits "indiscipline and a high-penalty count" cost the visitors in the second-half.
