SHANE WILLIAMS will fulfil two of his lifetime ambitions in one swoop tonight — playing for the Barbarians and running out at Wembley.

Football fan Williams faces Australia just four days after slaying the Wallabies in Cardiff.

The Ospreys wing wonder, 31, said: “Playing for the BaaBaas is one of the last things left for me to achieve in rugby.

“And I never thought I’d get the chance to play at Wembley. That’s going to be special.”

New Zealand captain Richie McCaw, 27, will also make his Barbarians debut.

He said: “Rooming with guys you normally beat the hell out of — or vice versa — is pretty good!”
