Roma coach Luciano Spalletti admits they have problems at the back after their 3-2 defeat to Genoa.

"These are statistics we are forced to consider and evaluate," sighed the Coach, who gave Nicolas Burdisso his debut less than 24 hours after completing the transfer from Inter.

"For example, Genoa's third goal came from a training ground exercise we had already seen them use against Odense on Thursday. We studied the tapes and were caught out anyway."
