The reality is that most of Roma's games with English teams over the last 17 years have been marred with similar fan violence. You would imagine that at some point over the last 17 years UEFA's shock should subside and become manifest in punishment.
In 2001, six Liverpool fans were stabbed around a UEFA Cup tie in Rome.
In 2006, three Middlesbrough fans were stabbed in the same city when attending a UEFA Cup tie.
A year later, five Manchester United fans were stabbed before a Champions League group game.
In 2009, a bus of Arsenal supporters was ambushed by Roma fans - they smashed the windows, stopped the bus, and one fan got on board and stabbed an English fan. Two months later, the Stadio Olimpico held the Champions League final.
In 2012, a Spurs fan received treatment for stab wounds following an assault by Roma fans.
And last year, Chelsea fans drinking in an Irish bar were attacked by masked Roma fans wielding metal bars.
