Paul O'Connell made his Six Nations punditry debut on the BBC for Ireland's dreary loss to France.
O'Connell felt the pivotal moment in France's 10-9 win was Guy Noves' decision to change his front row early in the second half.
Four minutes after half-time, Uini Antonio and Jefferson Poirot left the pitch to be replaced by Eddy Ben Arous and Rabah Slimani respectively.
That was 'the winning of the game' according to O'Connell.
