The Red Dragons stand a chance of winning the Six Nations for the second year in a row if they beat their rivals.
"They will have a nice warm welcome at the Millennium Stadium," BBC Sport quotes him as saying. "England are a very good side and it's great it has come down to the last game of the championship.
"We are delighted we have been able to refocus and gain momentum in a championship which is so important after the disappointment of the first-half display against Ireland.
"To come away from the last three games, which were away from home, and win is a credit to the players and the coaching team."
England will take on Italy on Sunday.
