FLORENCE - Esteban Cambiasso scored twice and set up Zlatan Ibrahimovic for the other as Inter opened their defence of the title with a 3-2 win at Fiorentina.
Ibra netted his first goal in black and blue after Cambiasso's first-half double, with Luca Toni scoring twice in ten second-half minutes to set up a tense finale.
Cambiasso broke the deadlock after ten minutes of play at the Artemio Franchi, finishing off a flowing passing move involving Dacourt, Crespo and Ibrahimovic with a low left-footed drive into the bottom right corner.
The Argentina midfielder celebrated his goal by pointing to the sky in honour of Giaincto Facchetti, for whom a minute's silence was observed before kick-off.
Cambiasso doubled his tally four minutes before half time, heading Figo's cross past Frey at the back post after the Portuguese winger combined with Ibrahimovic in a counter attack down the right.
Hernan Crespo had two good chances in the opening forty-five minutes. After sending a near-post header from Figo's free kick just over the bar, the Argentine forward forced a save from Frey with a blistering diagonal shot.
Ibrahimovic thought he had made sure of the points on 62 minutes when he volleyed in Cambiasso's assist to put Inter 3-0 up.
But last season's top scorer Toni made the Nerazzurri sweat for their victory, heading in crosses from Mutu and Reginaldo to throw Fiorentina a lifeline.
The Nerazzurri held on for victory, and Figo could have restored Inter's two-goal advantage on the stroke of full time but he dragged Crespo's cut-back wide of the far post.
