England's Andrew Flintoff has expressed his delight after being named in the World XI squads to play Australia in October's ICC Super Series.
The all-rounder has been selected for both Test and one-day duty.
"I might even get the chance to bat with Sachin Tendulkar, which would be fantastic. I'm going to be like a kid in a sweet shop.
"I'll be taking my autograph book and I won't quite know where to put myself," said Flintoff.
"It's great when I think back two years because I was still trying to play for England, never mind even being thought about for a World XI side.
"It's very flattering to be included and I've got the chance to mix with some of the best players in the world."
England paceman Steve Harmison joins Flintoff in the 13-man Test squad but there is no place for captain Michael Vaughan, who was in the previous list of 20 players.
There are two England players in the one-day squad, with Kevin Pietersen chosen along with Flintoff.
South Africans Graeme Smith and Shaun Pollock will captain the two teams.
And Flintoff is one of nine players picked to play for both sides - the others are Brian Lara, Muttiah Muralitharan, Shoaib Akhtar, Jacques Kallis, Pollock, Sachin Tendulkar, Virender Sehwag and Daniel Vettori.
"There are no weak links in either of these squads. Everywhere you look there is an outstanding player whose talent enriches the game," ICC chief executive Malcolm Speed commented.
"Graeme Smith and Shaun Pollock have been given an enviable number of options to cover all match circumstances."
The squads were chosen by a six-man panel chaired by former India Test star Sunil Gavaskar, and also including Sir Richard Hadlee, Clive Lloyd, Mike Atherton, Jonty Rhodes and Aravinda de Silva.
The Super Series begins with the three one-day matches at Melbourne's Telstra Dome on 5, 7 and 9 October.
The six-day Test will begin at the Sydney Cricket Ground five days later.
World coach John Wright reveals his team
Australia will name their squads following the current Ashes series in England.
"This is the ultimate sporting contest - the best team in the world against a team of the world's best players," said Cricket Australia chief James Sutherland.
"We have seen over the past month or so the intense excitement and interest that surrounds a genuine contest between two evenly matched teams.
"England are challenging Australia and we are going to see the likes of Andrew Flintoff, Steve Harmison and Kevin Pietersen taking them on again in October.
"This is a world-class event and Australian cricket is proud to play host. We believe it will be something fans will talk about for years to come, just as they recall the 1977 Centeneray Test and the 1971-72 Rest of the World Series," Sutherland added.
