AS Roma, in the lead at the start of the day, dropped to third after losing to Giuseppe Signori's superb winner at Bologna. It was its first road defeat of the season. Inter remains fifth after its fourth defeat of the season, tied with neighbor AC Milan - which beat Torino 2-0 Saturday - and a point behind Parma, a 2-0 winner at Venezia. Italy defender Fabio Cannavaro scored Parma's opener and Argentine Hernan Crespo took his personal tally to 10 in a match in which both sides had players ejected in the first half.

Van Der Sar was lucky to escape with a yellow card in the eighth minute when he denied Ivan Zamorano a goal by tripping him on the edge of the penalty area. The referee had no choice but to give the Dutchman his marching orders early in the second half when the goalkeeper used an outstretched arm to stop a Zamorano shot outside the area. In between, Alessandro Del Piero and Inzaghi combined superbly in the 19th minute to remind Inter manager Marcello Lippi what he gave up by resigning as Juve coach last February. Del Piero cut between Christian Panucci and Laurent Blanc before pulling back a superb pass for Inzaghi to give the home side a lead with his sixth goal of the season. By contrast, Lippi's side demonstrated why it has scored just twice on the road all season. Even after the home side was reduced to 10 men Inter rarely threatened replacement goalkeeper Michelangelo Rampulla. Juve's midfield pair Edgar Davids and Alessio Tacchinardi isolated Christian Vieri and Zamorano up front.

Croat striker Boksic took just 15 minutes to break Lazio's recent goal drought at the Olympic stadium, racing onto Sebastian Veron's pass to beat Francesco Toldo with a diagonal shot for his side's first goal on home turf since Nov. 7. Lazio should have put the match beyond the visitors long before Dejan Stankovic's second goal in the 71st minute. Toldo denied the Yugoslav and Roberto Mancini on either side of halftime.

Neighbour Roma had looked in the mood to continue its run of three straight wins when Vincenzo Montella's 10th-minute chip beat Gianluca Pagliuca but not the post. But Roma was stopped in its tracks by former Lazio favorite Signori, who did his old side a favor by volleying home Kennet Andersson's flick on with a superb bicycle kick in the 25th minute. Roma was unlucky not to grab a point when Marco Delvecchio hit the woodwork in the closing stages.
