The Italian champions' vice-president has underlined the importance of the upcoming Champions League encounter with the Spanish titans
The 67-year-old feels the Group H match is an encounter between the most successful team in history and the best club around at the moment, and has labelled the game the 'Derby of the World'.
"Barcelona are the best club in the world at the moment," Galliani was quoted as saying by La Gazzetta dello Sport. "However, Milan are the team with the most titles. The game could easily be described as the 'Derby of the World'.
"It's a great thing to start the Champions League with a match like this. It will be one big footballing feast."
Galliani also rubbished claims that the club would field only one striker against the Catalan side, following the absence of Zlatan Ibrahimovic, Robinho and Pippo Inzaghi through injury.
"Our history is 4-3-1-2. We've always played with two strikers and we'll play in that way this evening. Therefore, Antonio Cassano will be on the pitch," the vice-president told Sky Italia.
AC Milan have won seven Champions League trophies so far and finished runners-up on four more occasions. Only Real Madrid have won European club football's elite tournament more often, having recorded nine victories.
Barcelona have, to date, won four Champions League trophies and are the reigning champions, following last year's 3-1 win over Manchester United.
