Riquelme regards Iniesta as the best player in the world.
The Boca Juniors veteran said: "For me the best is Iniesta. There is no other like him. He is unique. If the game is locked, Guardiola sends him on. Left, right, in attack, he can do well anywhere.
"When I was there, he was 15 or 16 years old and trained with us. He made a big difference even at that age."
