All Blacks captain Richie McCaw is set to be offered a knighthood for the second time.

McCaw became the most capped international player of all time when he featured in his 142nd Test against the Wallabies on Saturday, leading New Zealand to a resounding victory as they retained the Bledisloe Cup.

The 34-year-old is expected to retire after this year’s World Cup, but will first be looking to lead the All Blacks to a second successive world title.

McCaw turned down an offer to be knighted after the All Blacks’ successful 2011 World Cup campaign, but regardless of the outcome at the upcoming global event, New Zealand Prime Minister John Key said he was in line to receive a second offer.

‘Whether he would take one, I don't know. The offer was there before and I can't imagine anything has changed,’ Key told TV3.

‘He's very bright, very resourceful and very brave. You put all that together and players play for him. He leads from the front. He knows he has to play well for them [the All Blacks] to play well. He understands what leadership is about. It's about doing rather than talking, he's got it all.’
