Former England scrum-half Matt Dawson has advised Stuart Lancaster not to pick Sam Burgess in his final squad.
The Bath player made his international debut in a warm-up victory over France, but was sin-binned for a pull back at the end of the first half.
Dawson told BBC Sports: "You can't take him to the World Cup for me. He played 80 minutes and credit for that. But the way the game went in the second half there was nothing for him to do.
"The great thing about Burgess is he doesn't make mistakes with ball in hand. But unfortunately, if you're going to be really picky, positionally he wasn't great.
"He played like a six rather than a 12. There are things that are instinctively he doesn't know what to do."
England play France in Paris next weekend.
