UEFA have blocked Roma fans from travelling to Rotterdam for the Europa League quarter-final against Feyenoord, seemingly in retaliation for the Italian authorities banning Dutch supporters.
This is the second time in only a few weeks that the local Italian authorities have imposed a blanket order banning the sale of tickets or entry to the stadium for all fans registered in one nation.
It comes after Eintracht Frankfurt supporters were barred from attending the Champions League Round of 16 with Napoli, though circa 700 made the journey anyway and wreaked havoc in the streets rioting against police and locals.
Feyenoord fans have a history with Rome, as their fans caused thousands of euros of damages to the 17th Century Barcaccia fountain in Piazza di Spagna.
Local authorities therefore announced yesterday that they were banning all people registered as residents of the Netherlands from attending the match at the Stadio Olimpico.
In response, UEFA today barred Roma fans from travelling to the first leg on April 13 at the De Kuip stadium in Rotterdam.
Both sides had hoped to have 1,200 supporters attending the away fixtures.
The decision to ban the Dutch fans was not made by Roma, but rather by the local police and prefect who fear crowd trouble.
