Laporta: Barcelona big winners from World Cup
There were eight Barca players in Spain's triumphant 23-man squad in South Africa, with seven (Carles Puyol, Gerard Pique, Xavi, Sergio Busquets, Andres Iniesta, Pedro and David Villa) starting in the final against Holland.
"Barca won the World Cup with a different shirt, or with the wrong shirt," Laporta told El Mundo in an interview.
However, Laporta conceded that Spain's victory was not all down to the Catalan club.
"The (playing) style was Barca's, but there were other players from other clubs that were fundamental," he said.
Laporta led Barcelona to 12 trophies in seven years as president of the Catalan club, but the former lawyer is now looking to begin a political career in Catalonia.
