Andy Farrell hopes to coax his grandchildren into supporting Ireland when he goes head to head against son Owen Farrell in Saturday’s crunch Grand Slam decider with England. Farrell junior has been restored to the visitors’ starting XV for the Dublin clash after being dropped to the bench ahead of last weekend’s 53-10 humiliation at the hands of France. The father and son are well-versed in being in rival camps but their relationship adds an intriguing sub-plot to the St Patrick’s weekend showdown as the hosts seek to clinch a Guinness Six Nations clean sweep. Ireland head coach Andy admits some subjects have been off limits during recent conversations with England’s skipper as he joked about converting Owen’s young sons Tommy and Freddie into Irish fans.
