World Cup winner Lawrence Dallaglio believes back-row Sam Burgess has "an aura about him" and can be a success for England in the upcoming tournament.
The 26-year-old Bath star, who recently switched from centre to the blindside flank, was retained in the national squad for their Denver training camp.
And Dallaglio is confident the league convert can play a key role for England.
"He might force his way into contention which again is quite exciting. I've been following his progress, he has presence, an aura about him," he told BBC Points West.
"To play for your country you need to have involvement in the game and since he has moved from centre to the back-row we've seen him have much more.
"I like the guy. I'm quite surprised no-one has tried to properly lay one on him yet. He's an outstanding prospect and I'm sure he's causing the coaches a headache or two."
Many have spoken about the benefit of home field advantage that England will have in 2015 and Dallaglio joined that group ahead of the event.
"It's a pretty tough tournament but as the host nation, England should go in there feeling very proud and with a great opportunity," he said.
"I think we are genuine contenders by nature of us playing at home. We are probably the most inexperienced team of all the genuine contenders and I think that may count against us.
"What this rugby World Cup tells you is hardened, seasoned veterans tend to do quite well as you need to understand how to deal with pressure.
"But they have home advantage and talented players and I'm expecting big things of England.
"If they can come out of their group as winners they really do have a big chance and then we can dare to dream."
