Jonny Wilkinson believes England need to improve their discipline if they are to have any chance of winning the World Cup, something they are 10/1 with bookmaker to do.
England have conceded 25 penalties in their first two games of the tournament but have won them both – against Argentina and Georgia.
Wilkinson is determined to cut that figure down against Romania on Saturday and Scotland, 200/1 to win the tournament, seven days later.
Dylan Hartley and Dan Cole have both been handed yellow cards while Courtney Lawes has been suspended, and Wilkinson said: “Guys are understanding now that once is a mistake, twice is a lot more than that and three times just can’t happen.”
