The Lazio president claimed that Borussia Monchengladbach fans were not actually stabbed in the build-up to the clash between the two sides on Thursday
Three Fohlen fans were wounded in Rome on Thursday, but the 55-year-old has played down the severity of the incidents.
"I would like to put these incidents in context,” he told Sky Sport Italia.
"I spoke to the police and was told two of them weren't actually stabbings, as the people barely noticed the contact.
"I would also urge the media not to label the protagonists of all these incidents as 'Lazio fans'. Rome is a metropolis and as such is inhabited by bad people.
"For example, there is no suggestion so far that those behind these incidents were part of Lazio’s organised fan groups.
