New Wales defence coach Mike Forshaw has told his players they must improve their "poor" discipline to prevent Scotland wing Duhan van der Merwe leaving a "trail of destruction" in his wake this Saturday.
Wales endured a horrible first 40 minutes in Cardiff, finding themselves 27-3 down at the interval during their crushing Six Nations defeat to Ireland.
This was in no small part down to their shocking discipline with Wales conceding 15 penalties along with 33 missed tackles.
