South American champions Boca Juniors added the Toyota Cup to their collection of trophies on Sunday with a victory over Champions League winner AC Milan after a penalty shootout in Yokohama.

Andrea Pirlo, Clarence Seedorf and Alessandro Costacurta all missed their spot-kicks to hand Argentina's Boca Juniors the unofficial title of world club champion (3-1 on penalties) after a numbingly dull game had ended 1-1 after extra time.

"It was a game between the champions of South America and Europe, so logically it turned out to be a battle," said Boca coach Carlos Bianchi. "Towards the end of extra time I felt the Milan players were hanging on for penalties," he added. "I'm very proud of the way we kept attacking. We were even more aggressive with our penalties."
