Mike Tindall has claimed there is no way Wales will win the World Cup unless they can ‘change the way they play.’
The former England captain and World Cup winner in 2003 joined host Alex Payne and Mirror rugby correspondent Alex Spink on the latest episode of House of Rugby and analysed the Six Nations champions' chances.
Tindall believes Warren Gatland's side, who are on a 14-match winning streak after securing the Grand Slam last month, will not be able to rely solely on their defence when they get to Japan later this year.
Before the Six Nations, they were only considered outside contenders for rugby's biggest prize, but are now much more heavily fancied.
Wales were worthy winners of the third Grand Slam of Gatland's tenure and in the eyes of many, they have now surpassed Ireland and England as the northern hemisphere's best World Cup hope.

Tindall claims that Wales were boring to watch during the competition even though they won. Their biggest win was against Ireland 25-7 and England actually scored 34 more points than them.
Although they showed resilience during the Six Nations, the former World Cup winner still thinks their current style of play will not serve them well when the games come thick and fast in Japan.
"Watching them play through the Six Nations, if they play that way, which literally could bore anyone...” Tindall said.
“I don’t think they can go into a short format tournament, over six weeks and seven games and deliver just on defence.”
When questioned why he doubts Wales credentials, Tindall explained the reason he couldn’t see them follow up their Six Nations triumph with a World Cup win was their inability to score tries.
He continued: “Rugby is all over the place at the moment in terms of who can beat who.
"I'm happy to be proven wrong and see a northern hemisphere side win the World Cup.
"When we won the World Cup, all the previous winners were built on best defence won. I don't think we live in that era now.
"There's f**king no way that Wales will win the World Cup.”News Now - Sport News
