Jac Morgan’s men had to dig deeper than ever before, pulling off a World Cup record 252 tackles before beating the Fijians 34-28 in Bordeaux, and the goal now is to make it two from two in Nice on Saturday.
“There was a hell of a relief at the end against Fiji, but the next thing is Portugal. We need to play better, we need to be more accurate,” said Humphreys.
“There is still massive room for growth for us, but it’s better doing that off a win rather than a loss. We’re not thinking about what could be.
“We know what’s definitely going to be and that’s Portugal in a few days time – and it won’t be an easy game. We’ve watched them and they are a tough side to play against.
“We don’t see this as pressure off, it’s just the next game and we have to perform.”
