The former England international Mike Tindall expects England to reach the World Cup final and believes only the All Blacks stand in their way of lifting the Webb Ellis trophy on home soil.
Stuart Lancaster's squad head to Denver this weekend for two-weeks of high-altitude training before they host France at Twickenham in the first of three warm-up games ahead of the World Cup.
England have been drawn in the same pool as both Australia and Wales for the tournament which starts in September with only two of the three progressing to the quarter-finals.
England will avoid world champions New Zealand until the final at Twickenham providing they top their pool.
Tindall, who was in the team that won the World Cup in 2003, expects England to deliver in front of their home support.
"If I put my hand on my heart I don't see England losing," Tindall told Press Association Sport.
"With the home advantage, and the leaps and bounds they made at the Six Nations, they are in a really good spot right now.
"Their strength in depth - especially through the pack - is incredible and now they have a backline that is backing them up."
He said the high performance level and the side's consistency was likely to put them in the final.
"You would put money on New Zealand being there to face them and then it is just a one-off game, but England have that game to beat them."
