Tickets for Rome Derby - Any info?

[cocobeab]

I'm hoping to be in Rome next month, over the weekend of the Lazio Roma game 7/11. Can anyone with any knowledge or prior experience let me know how easy it might be to get a ticket for the game, either in advance or once i'm over there. Would obviously rather avoid agency fees if it can be done. have succesfully managed this in a good few other european cities fingers crossed JKB can assist with the Rome bash too. Anyone .......
