British and Irish Lions coach Andy Farrell has suggested the New South Wales Waratahs may have deliberately over-watered the pitch at Sydney's Allianz Stadium ahead of Saturday’s match in which the tourists struggled to a 21-10 win.

Lions head coach Andy Farrell accused the NSW Waratahs of dirty tricks by heavily watering the Allianz Stadium pitch prior to their error-strewn 21-10 win in Sydney.

Making an issue of the wet pitch wasn't a good moment for Lions head coach Andy Farrell, but Saturday's match might have been a good night for his son Owen.
