The 38-year-old spoke of his involvement in the prestigious tournament two years ago, whilst also insisting that he prioritised Boca Juniors over his rivalry with Riquelme
The 38-year-old hung up his boots in 2011 after more than 500 league appearances with Estudiantes, Villarreal, Betis and most notably, Boca Juniors where he won six league titles as well as two Copa Libertadores titles.
The one-time South American Player of the Year revealed however, that despite being selected for the Argentina squad in the 2010 World Cup, there were also some unsavoury moments, including his well-documented rivalry with Juan Roman Riquelme.
"The most important memory in my career is the World Cup in South Africa. Diego Maradona gave me the opportunity to be there and be involved. I'll take that as the image of my football life," Palermo told Cadena Cope.
"Though not everything was beautiful during my time in Argentina, when I played for Boca with Roman Riquelme. I prefer his clarity, his vision, his quality. He led Villarreal to the semi-finals of the Champions League, he is a player who made his mark to the Boca fans.
"But we are not all equal and we don't all think in the same way, but I always put the group first rather than the particular issues I had with Roman."
Palermo also touched upon his past with the Argentine giants, revealing his affinity with the Boca-River Plate derby.
He continued: "I have many nicknames but I prefer the one I got from Carlos Bianchi, 'El Optimista del gol'. it stays with me, every day, every training session. I went to bed thinking about what goals I could score in the game the next day."
"I liked playing for Estudiantes, but playing in a Boca-River [derby] is the most beautiful in the world."
