Ali Williams - 2011 Rugby World Cup winner, and former All Blacks and Blues lock - joins Martin Devlin on It's Only Sport, looking ahead to Saturday night's Super Rugby Pacific final between the Blues and Chiefs at Eden Park in Auckland. It's the first time ever the two sides will meet in a Super Rugby finals match let alone a decider, with there being five of the previous 22 competitions won between them (the Blues in 1996, 1997 and 2003, and the Chiefs in 2012 and 2013). Williams and Devlin discuss the former's experiences in Super Rugby and World Cup finals, how the occasion differs from a regular rugby game, how special this weekend's match is for the city of Auckland, and more.
