The veteran No.10 believes that all young players must watch the world's best in order to improve, and gave the example of the Blaugrana star as one man he observes closely
The former Barca and Villarreal playmaker returned to the Boca first team on Wednesday after missing several games through injury, and was on top form as he scored in the Argentine side's 2-0 Copa Libertadores victory over Zamora.
The Xeneize qualified second in their group behind Fluminense, and their reward is a meeting with Chilean side Union Espanola in the last 16.
Speaking on Thursday night, Riquelme showed his humble side as he admitted that, as a professional footballer, he would never stop learning new things from the best in the world.
"I always tell the young players that they have to be learning every day. For example, by watching other players. I watch Iniesta and I realise that I could be doing new things still," the veteran explained in declarations published by La Razon.
"We all have to be less arrogant."
Returning to the subject of Boca's Copa chances, Riquelme affirmed that his goal was to take the Buenos Aires giants at least to the final.
"I hope that Boca can make it until the very end. But to do that, we have to play exceptionally well. Boca are doing well, it is not easy to play every three days but we have lost three games and in all those the team that won has not been better," he stated.
"They have beaten us thanks to set-pieces. Even when we don't play well the opponent has not outplayed us, that gives us confidence."
Boca will be back in action on Sunday, when they travel to Cordoba to play Belgrano.
