Lazio 3 - 1 Roma
Di Canio 29 (L), Cassano 68 (R), Cesar 73 (L), Rocchi 84 (L)
Stadio Olimpico
Paolo Di Canio's spectacular volley inspired Lazio to a memorable 3-1 Derby della Capitale win over rivals Roma, their first in the last ten editions of this showdown.
There can be few more difficult debut games than the Rome derby, but new Lazio Coach Giuseppe Papadopulo went into this clash as a former Biancocelesti player, so he was prepared for the fiery atmosphere. It was further fuelled during the week by the two club captains trading insults in the press.
Papadopulo was forced to deal with several injuries to Fernando Couto, Oscar Lopez, Antony Seric and Luciano Zauri, so Giuliano Giannichedda moved into a new central defensive position, while Roma were dealt a massive blow by top-scorer Vincenzo Montella's ill-timed one-match ban.
There was a great chance for Lazio after 49 seconds, as Tommaso Rocchi pounced on an Ivan Pelizzoli fumble, but he was unable to make the most of the slip.
As expected, it was a fiery encounter and Emanuele Filippini was booked for going through the back of Mancini within eight minutes.
Lazio were more dangerous in the early play and Pelizzoli only pushed a powerful Cesar snapshot round the post with some difficulty. Rocchi then robbed Matteo Ferrari and almost got his cross in to Paolo Di Canio in an unmarked position.
A scuffle broke out between Francesco Totti and Antonio Filippini when the Lazio man charged in with a crunching tackle, but the Biancocelesti were clearly playing better and it took a spectacular Christian Panucci header to prevent Cesar pushing in Di Canio's chip with Pelizzoli beaten.
Roma hit back on 23 minutes with a Simone Perrotta header comfortably saved, but their defence was again exposed by Cesar and the Brazilian's poor first touch allowed Traianos Dellas to recover.
The goal was in the air, but few expected one quite so spectacular. On the half-hour mark Fabio Liverani chipped up a pass for Di Canio, who got inbetween the two central defenders and hit a perfect volley over Pelizzoli. The returning hero could not have asked for a better way to mark his first Derby della Capitale goal since 1989, even if he angered Roma supporters by celebrating under their end.
The tension rose further with a series of tense scuffles between the players and a list of yellow cards. Totti sprinted forward and drilled his finish wide from the edge of the box, but Lazio again went close with Liverani's deflected free kick.
Gigi Del Neri had to make changes and introduced teenage striker Daniele Corvia in place of defender Matteo Ferrari. Their attitude was certainly different, as within seconds Leandro Cufre's diving header was charged down by Massimo Oddo's body.
Moments later there was some splendid interplay and Totti's deflected effort was pushed away from Angelo Peruzzi by a Mancini handling offence, for which the Brazilian was booked.
Under-21 international Aquilani replaced the injured Perrotta and Roma had an extraordinary opportunity to draw level. Totti's floated free kick took Peruzzi by surprise and Cufre' only had to get his shot on target from eight yards, but scuffed the ball well wide.
There were penalty appeals for Daniele De Rossi's last-ditch challenge on Antonio Filippini, which sparked a furious response from the Lazio fans and play was halted for several minutes as objects and flares were thrown on to the pitch. A firework exploded close to Totti and referee Paolo Dondarini, leaving both dizzy and in need of treatment.
Play resumed and on 69 minutes Roma grabbed an equaliser. Panucci found space down the right flank and put in a mid-height cross for Antonio Cassano's glancing header at the near post. The Italian international had to crouch in order to get the right contact from six yards and showed quick thinking to get on the end of the cross.
However, the scoreline lasted only a few moments before Lazio restored their lead. The defence was again distracted, leaving Cesar all the time he needed to prepare for his half-volley into the far corner of the net.
Rocchi sprinted through the centre of the Roma defence and went round Pelizzoli, but the goalkeeper succeeded in narrowing the angle and the chance went begging.
The result was put beyond doubt with six minutes left on the clock, as Rocchi sprung the offside trap and made the most of Pelizzoli's wayward rush off his line to walk the ball into an empty net.
There were seven minutes of stoppages due to the number of yellow cards and the flare incident, but a disheartened Roma was unable to get back into the game. There was time for Di Canio to be granted a standing ovation from his home fans, something that irritated Dellas.
