Well I'm only 16 so I haven't been following football for a huge deal of time. Only like 6 years (would have been just before the 2006 World Cup) but I would have to agree with your selections of Alessandro Nesta and Luis Figo but my full XI would probably be:
Edwin van der Sar (Sorry, can't go past my favourite teams goalie
)
Don't really have a favourite left back but I'd have to go with Alessandro Nesta, Fabio Cannavaro and Gary Neville as my favourite backs (I was a fan of the Italian backs during the 06 World Cup)
My midfield would have to be Arjen Robben, Tim Cahill (Can't go past the Aussie legend
), Deco and David Beckham (Liked him up to the point when he left United) with Luis Figo close behind him.
Up front, I would have to go with Andriy Shevchenko as my favourite, with Zlatan Ibrahimovic a close second although John Aloisi would need to be in there just for the best moment when he scored the penalty to take Australia through to the '06 world cup.
But yeah, that would probably be my XI.
