Wales captain Alun Wyn Jones says his side must continue to improve as everyone now knows what they are about ahead of the World Cup.
The Welsh produced a dominant display to secure a 25-7 victory over Ireland on Saturday to wrap up a Grand Slam in Warren Gatland’s final Six Nations game in charge.

With Wales beating all of the northern hemisphere’s best, Jones knows his side can’t rest on their laurels if they are to enjoy a successful World Cup in Japan later this year.
He told the BBC: “Anything can happen when you work hard and you’re a proud nation and we’ve shown that. “Warren’s the man at the top and we’ve been under pressure but he’s always been unwavering. He’s got a bit left on his contract but I’m sure we’ll miss him when he’s eventually gone.
“At times we’ve been unconvincing so we like to think there’s still potential in us. We’re well aware we’ve just put a big target on our backs before the World Cup.”
