Rugby World Cup 2015: Support from home 'overwhelms' All Blacks

The support for the All Blacks is flooding into their training base outside London as they prepare for the World Cup final showdown against Australia, with midfielder Sonny Bill Williams today describing it as "overwhelming".

Messages and best wishes are starting to cover the walls of their team room at their Pennyhill Hotel base which the players will use as inspiration as they attempt to defend their title at Twickenham on Sunday morning.

Normally England's home, the All Blacks have this week taken it over the hotel and training facilities in Bagshot, Surrey, as they get ready for their first World Cup final against their neighbours, and reminders of home will not be in short supply.

Williams tweeted today: "The support is overwhelming", with fullback Ben Smith admitting the team are getting a sense of the anticipation building on the other side of the world.

"I imagine they'll be pretty excited back home," Smith said. "We're excited as players to get out there and play the game.

"It's great to have all the support from back home - we definitely feel that support.

"There are things that pop up in our team room that we have a look at. Obviously people send you messages of support and you're really grateful for all the support we're getting from back home. It means just as much to them as it does us."

The players' team room at their luxurious base is a private area where they will hold meetings and, potentially, have snacks between their meals. It is an area in which they can mix away from prying eyes.

The support is reaching a crescendo, just as the volume of the crowd chanting for the All Blacks in their tense 20-18 semifinal victory over the Springboks at Twickenham at the weekend did.

Steve Hansen's men have never heard such chanting at England's home, with veteran midfielder Conrad Smith this week saying it spurred them on as they defended their slim lead against a Boks team which saved their best of the tournament for last.

Halfback Tawera Kerr-Barlow, who was born in New Zealand but lived in Australia's Northern Territory for much of his youth, said he had received support from his Australia mates, who had a foot in each camp.

He added of New Zealand's trans-Tasman rivalry: "We have the Bledisloe between us which is taken very seriously by both countries, and I think because we're so close to each other, through any sport really we're natural rivals. I suppose it's fitting we end up in a World Cup final together.

"When I was younger, Australia were going through quite a good period in their rugby, so obviously our family friends used to give us a bit of grief. Everyone knows it's a massive rivalry between us. It's a World Cup final and everything is up for grabs so that will add to the occasion."
