Throwback photo of lionel messi in 2000
I'm afraid that's not possible!
Lionel Messi was born on June 24, 1987, which means he was only 13 years old in the year 2000. At that age, he was still a young boy playing for Newell's Old Boys in Argentina, and not yet a professional footballer.
The earliest photos of Messi as a professional footballer are from around 2004-2005, when he was playing for FC Barcelona's youth team and eventually made his debut for the first team in 2004.
If you're looking for a throwback photo of Messi, I can try to find one from his early days as a professional footballer, but it won't be from 2000!
