Wales’ emphatic victory over Ireland secured a famous Grand Slam Six Nations win, one that never looked like a possibility at half-time during the tournament opener against France.

Warren Gatland’s men started off slowly in the Six Nations but they certainly got up to speed very quickly and came out victorious in all five matches played.

With the trophy now in the bag, and with the pride of a Grand Slam boosting spirits even further, Wales will head into the World Cup in high spirits and with a genuine chance of going all the way in Japan.

However, despite the great tournament and the continuation of the winning streak, Wales know that their are still lessons to be learned ahead of the World Cup.

I’ve looked back at the Welsh Six Nations performance as a whole to find things that we now know about the team, whilst identifying a few questions that still need answering.
