Chris Robshaw has warned that Wales could spring a surprise on England when they collide in Cardiff later today.
“Why am I nervous? Partly because Wales have improved massively in the past two games,” Robshaw told Planet Rugby.
“Partly because they have had an extra day of recovery, which is significant at this end of the tournament.
“But mainly, because experience has taught me the effect England coming to their home with the chance of winning the title under that roof, has on the Welsh.
“In 2013 we were thoroughly beaten. We spoke beforehand of what it was likely to be like, what we would likely experience, but we were way off.
“We didn’t truly understand the psyche of what it meant to the Welsh people for an English team to win a championship, to win a Grand Slam, in Cardiff.
“It was a massive learning curve, going into a real hostile environment and getting put away like that.”
