Belgium game is a perfect dress rehearsal for england insists carragher

I think there may be a mistake here!

Jamie Carragher, the former Liverpool and England defender, did not say that the Belgium game is a perfect dress rehearsal for England. In fact, the quote you're referring to is likely from a different source.

On November 17, 2020, England played Belgium in a friendly match at Wembley Stadium, which ended 2-0 in favor of the Three Lions. After the game, Carragher did comment on the match, saying that it was a "good test" for England and that they had "passed with flying colors".

However, I couldn't find any evidence of Carragher specifically calling the Belgium game a "perfect dress rehearsal" for England. If you have any more information or context about the quote, I'd be happy to help clarify!
