European football's governing body acted after rival sets of supporters threw missiles at each other and clashed with Italian police, who were heavily criticised for their behaviour by United supporters following the incident at Stadio Olimpico in Rome.

Roma were fined 47,000 euros with United having to pay 21,300.

The clubs have the right to appeal the decision imposed by UEFA's control and disciplinary body.

Roma won that first leg 2-1 before a 7-1 drubbing in the second leg at Old Trafford.

At a separate hearing UEFA announced that European champions Greece must play their next two Euro 2008 qualifiers against Hungary and Moldova at least 250km away from the Greek capital Athens.

This punishment follows trouble at the Georgios Karaiskakis stadium during Greece's 4-1 defeat by Turkey which included fireworks and missiles being thrown, racist banners displayed and a general lack of organisation.

The Greek football federation has also been ordered to ban extremist supporter groups from matches of the Greek national teams and to pay a 61,000-euro fine.

And the Norwegian Football Association and the Football Federation of Bosnia-Herzegovina picked up fines of 18,300 and 36,600 euros respectively after crowd trouble at their Euro qualifier in Oslo which Bosnia won 2-1.
