Inter Milan beat Siena 1-0 today to seal its fifth consecutive Serie A title and move two-thirds of the way to a possible treble.
Diego Milito took a pass from Inter captain Javier Zanetti and scored his 22nd goal of the season to break the deadlock in the 57th minute at Siena's Artemio Franchi stadium.
Inter finished with 82 points, two more than AS Roma, which won 2-0 at Chievo Verona.
Roma scored both of its goals in the first half and had its hands on the title before Milito saved Inter.
Inter beat Roma in the Italian Cup final, and Jose Mourinho's side will face Bayern Munich in the Champions League final Saturday as it attempts to become the first Italian club to achieve the treble.
