The Red Rose can secure a Grand Slam triumph if they win in the Welsh capital at the weekend, following their 18-11 victory over Italy on Sunday which extended their unbeaten run in the competition.
However, a winning margin of eight points or more will see the Dragons retain their crown, and Davies is adamant that Wales can snatch the title from England's grasp.
"When the pressure is put on us we just thrive on it," said Davies. "This group of players are used to a big-game environment.
"The fact that people wrote us off after the first game, to come back with three away wins, the boys were extremely pleased with that. We understood that we could cause problems in this Championship and do very well.
"We've been in these big games before and we have experience in them. We have experience from last year's Grand Slam and the semi-final in the World Cup."
Wales go into the game off the back of a 28-18 win over Scotland.
