Wayne Pivac believes a step-up in intensity in training means his Wales side will come up with the goods in their Six Nations clash with England.
Wales have lost their last two Tests, going down to Ireland and France respectively heading into Saturday's contest at Twickenham, where they have not won in eight years in the championship.
However, Pivac has sensed a change in mentality from his side during their recent training sessions, with the coach singling out captain Alun Wyn Jones as the epitome of this shift to a more intense approach.
"The level of intensity has noticeably gone up in training, certainly in the live stuff and it has been no holds barred," Pivac, who replaced Warren Gatland after the Rugby World Cup, told reporters.
"No one has been holding back. That tells me a big performance is coming.
"You've only got to listen to Alun Wyn during the week. The intensity is there in his voice and everything he's done in training. He's led from the front."
Saturday's game will be the first time Pivac has gone up against England as a coach, though he does not think Eddie Jones' team will hold many surprises for his side.
"With my background coming from New Zealand we look at England like the Welsh do," said Pivac.
"They're a strong team, one of the world leaders, and a very capable team as we saw at the World Cup against the All Blacks and last week against Ireland. They put away two of the top teams in the world comfortably.
"There is a healthy respect, but it's a game we're looking forward to. Me included."
