( CNN ) -- AC Milan have moved up to second place in the Italian Serie A table , just four points behind city rivals Inter , after Brazilian international Alexandre Pato scored a last-gasp winner to give them a 2-1 victory at Fiorentina . Pato fired home Ronaldinho 's cross in the final minute to ensure the Rossoneri moved above Roma in the title race . Fiorentina opened the scoring in the 14th minute when former AC Milan striker Alberto Gilardino tapped-home after Milan had not dealt properly with Stevan Jovetic 's pass . But substitute Klass-Jan Huntelaar levelled with 10 minutes remaining , after a superb one-two with Ronaldinho , before Pato won it for Milan at the death . Meanwhile , in the evening 's other Serie A match , Udinese fought back to claim a hard-fought 2-1 home win over Cagliari . Brazilian striker Jeda headed Cagliari into a third-minute lead but two goals in as many second-half minutes from Alexis Sanchez and top scorer Antonio Di Natale marked coach Pasquale Marino 's return to the club with a victory .
