Winterling says Totti is a key part of the club's push to improve it's profile around the world.
"Francesco is crucial. His jerseys are always the most sold, he is known throughout the world, has enormous value as a trademark and not just as a player," said Winterling.
"We are trying to increase the brand and target new markets," he said, referring to the Indonesian market, "but we cannot deny that Francesco is the best known and loved."
