Wales defence coach Shaun Edwards revealed that they are focusing on discipline ahead of their clash with England at the Principality Stadium.
Wales host England in what promises to be a match of epic proportions as Wales look to change their fortunes of last year when they lost 27-13 at Twickenham.
Edwards said they are focussing on bringing their penalty count down to avoid conceding points through England’s long-range kickers.
“The big thing for us, and the big thing that Rob (Howley) really drives, and he drove it a lot in 2013 when we won the Championship, is discipline,” Edwards told reporters.
“We are down to seven penalties a game in the last five games and that’s massive with the standard of goal kickers that are going to be on that pitch.
“Owen Farrell and Elliot Daly kicking them from the halfway line while obviously our kickers are not bad in Leigh Halfpenny and Dan Biggar, so discipline is a massive part of the game.
“A big part of who is going to win this Six Nations is keeping 15 players on the pitch. We did that against Italy, our discipline was excellent and that is vital.”
