Sure I've forgotten some but:
1. Sir Chris Hoy (Track World Championships 2012)
2. Usain Bolt (Olympics 100m heats 2012)
3. Ronaldo (Southend Utd 1 - Man U 0)
4. Sachin Tendulkhar (England vs India at Oval 201(1?)
5. Frank Lampard (Chelsea 1 - Southend Utd 1 / various England games)
Others: Alastair Cook, Jessica Ennis, Victoria Pendleton, Laura Trott, Petr Cech, Wayne Rooney, Phil Taylor, Pistorious...
I think I've seen the winning Ashes team when they did that bus tour through London but I can't be sure.
I guess I ought to count Beckham too, but the time I saw him he was a barely used sub. Still, given his exploits I should include, were it not for Lampard being astoundingly good all 4 times I've seen him play.
