Was he playing for Man Utd that year they hammered Roma?
Googled it, he didn't play in any of the two legs. I can't see Totti switching shirts with the 232423th choice CB anyway
They played them two years running.
He played in this one:

Found the highlights on youtube and Roma wore the same kit as in the photo. Good sleuthing.
Totti didn't play though?
