Player ratings: Johnny Sexton as efficient and controlling as ever as he reaches century

Japan had no answer to Ireland's physical dominance and power at the maul and, when you don't have an answer for those core areas of the game, it's very difficult to win

Ireland were outstanding. Like, seriously good.

They won every collision, first and foremost. Not just in a general sense either. Every single collision in attack and defence moved the way Ireland wanted it and that allowed free reign to offload, play with real tempo and imagination and, ultimately, put this game well beyond Japan inside the first 20 minutes.
