ROME, May 16 (Serie A) - Lazio failed to win a place in next season's Champions League despite their triumph at Rome's Stadio Olimpico on the final day of the Serie A season.
The result was also a poor one for Modena whose relegation to Serie B was duly confirmed.
Goals from Bernardo Corradi and Cesar crushed Modena's hopes, despite the visitors reducing the deficit with eight minutes to play thanks to a penalty from Nicola Amoruso.
Lazio, who only four days ago clinched the Coppa Italia trophy, not only needed to win to reach the Champions League but also for Inter Milan to lose at Empoli.
It was not to be for Lazio, as Inter's 3-2 win at Empoli meant that the Romans had to settle for sixth position in the standings - Parma secured fifth spot by beating Udinese 4-3.
Lazio's much-admired coach Roberto Mancini watched what may yet be his last game in charge from the stands after earning a touchline ban.
With the home fans in celebratory mood, Lazio got off to a convincing start forcing two early corners in the opening minutes.
With seven minutes played, Lazio had a goal disallowed after Brazilian Cesar was correctly ruled to be in an offside position.
Two minutes later, the visitors had their first opportunity of the game, but striker Massimo Marazzina fired straight at goalkeeper Angelo Peruzzi after doing the hard part by beating three challenges.
Marazzina was again involved shortly afterwards, but his well-executed acrobatic kick inside the area went wide of Peruzzi's far post.
Despite Modena's efforts, it was the home team who went ahead in the 16th minute thanks to Corradi.
Cesar, on the left wing, fed Corradi inside the area, and the striker fired past goalkeeper Adriano Zancope.
Midway through the first-half, Lazio could have doubled their advantage after Cesar's close-range header hit the crossbar.
Nine minutes before the break, Zancope denied Lazio a second goal of the afternoon after a fantastic dive to his right to parry defender Sinisa Mihajlovic's powerful free-kick.
Desperate Modena attempted to get back in the game after the re-start, but it was Lazio who struck again with the influential Cesar extending his team's lead in the 48th minute.
Corradi failed to collect Claudio Lopez's cross, but Modena's defence only cleared as far as Cesar who did not fail from close range.
Modena boss Gianfranco Bellotto then made two substitutions, with Vedin Music and Stephen Makinwa replacing defenders Fabio Vignaroli and Jacobo Balestri, in an attempt to give his side more power in attack.
However, it was Lazio who initially seemed to benefit.
Lopez should have made it 3-0 after an hour's play. Substitute Massimo Oddo's cross found an unmarked Lopez whose header went wide of Zancope's goal.
With seven minutes left to play, Modena were handed a golden opportunity to reduce the deficit when the referee pointed to the spot after Lazio captain Giuseppe Favalli had cleared the ball with the aid of his arm.
Striker Amoruso's perfect strike beat Peruzzi and more importantly, brought the outcome back into question.
However, Lazio were solid from that point on and looked determined to end the season on a winning note.
Lazio players Favalli and Jaap Stam, who almost certainly played their last games for the
received an ovation as the team ended with a lap of honour.
