Mike Ruddock is convinced Wales' armoury contains every weapon required to beat Ireland next weekend and seal a first Grand Slam since 1978.
Wales destroyed Scotland in 40 minutes of blistering running rugby on Sunday to set up a dramatic RBS 6 Nations finale in Cardiff.
The Irish can still lay claim to the championship with a victory over Wales, as can France who travel to face Italy in Rome. Both sides played on Saturday so will have enjoyed an extra 24 hours of recovery before the final weekend.
But Ruddock has complete belief that everything is in place for his players to emerge with all the spoils.
''We have planned for this since last June. I sat down, looked at the dates and worked out the way we would structure the whole situation,'' said Ruddock.
''A lot of planning has gone into what we are going to do this week. There will be a big emphasis on recovery, a big emphasis on debriefing our game, a big emphasis on doing our homework on Ireland and focus on our game-plan.
''All the external stuff, the hype and all that goes on elsewhere, will be on the outside of the camp.
''Everyone has worked to give these players the best possible chance. The players are a great credit to the nation. They play with great confidence, they have a belief in the game-plan and each other.''
The Welsh squad are now used to separating themselves from the expectations of their supporters, which have grown week on week as the side continued to find new ways of winning matches.
Against England they left it late, Italy was a more comfortable while France forced them to stage a stunning second-half comeback.
on Sunday, Wales hit their straps right from the off. Tries from Ryan Jones, Rhys Williams, Shane Williams plus two from Kevin Morgan opened a remarkable 38-3 lead by the interval. Murrayfield was stunned.
Rhys Williams added another early in the second-half before Scotland staged a comeback that produced tries for Andy Craig, Rory Lamont and Chris Paterson and was valiant but ultimately fruitless. The game had long been up, and Wales won it 46-22.
Wales' Grand Slam chances were endorsed by Scotland coach Matt Williams, who described them as the best side his team had faced this championship.
''Their passing out of hand, their continuity, their support play and desire to get there is first rate,'' said Williams.
''They deserved the win and deserve to be undefeated in the tournament leading into next week's game in Cardiff.
''Ireland won't give them the latitude that we gave them in the first half but if they play like they did (on Sunday) they will be very hard to stop.''
