The Giallorossi are facing Liverpool as part of their preseason tour.
"It will be a fascinating match between two great clubs and what's more Boston is the city of our President. It was only right to participate in this event. My legs are holding up better, but still very tired seeing as we are doing heavy physical work," said Totti.
"Boston is a beautiful city, though we have so far been mostly training and haven't been able to see too much of it."
