“That was an incredible debut,” said Townsend, after Scotland ended their 38-year wait for victory at Twickenham. “To come into a squad you’ve not trained with before, meet players for the first time and integrate to our way of playing – we saw his skill-set, his confidence, his maturity. “You don’t expect someone on their debut to have such an accomplished start, especially against England of all teams and in a place where we’ve not won for so long. “He got on the ball a lot in the early stages of the game, and then he did very well when he was on the ball. He put in a lot of really good carries, smart passes and was very impressive all around.
