Wales "grow an extra arm and leg when they're playing in the Principality Stadium" and they will be the best versions of themselves against Scotland as they bid to right the wrongs from Dublin.
That's the opinion of Scottish head coach Gregor Townsend, who is braced for a strong Welsh reaction this weekend after their 29-7 defeat to Ireland in the opening round of the Six Nations last time out.
While the Scots beat Wales in Llanelli behind closed doors in October 2020, they head to Cardiff - on the back of a dramatic Calcutta Cup win over England - searching for their first victory in the Welsh capital in 20 years.
