Despite taking the lead thanks to Alen Stevanovic's wonder goal, Torino lost concentration and conceded two late goals to suffer their third defeat of the season.
Toro made just one change from the side that convincingly beat Pescara last weekend, as Simone Verdi replaced Giuseppe Vives, as the away side reverted to their normal 4-2-4 formation.
It was the home side who made the better start, and within the opening couple of minutes, Francesco Stanco was unlucky to see his diving header hit the bar. Torino responded well as they also hit the woodwork from Simone Verdi's curling free kick.
Alessandro Sgrigna - who scored two goals against Pescara last Saturday, showed some nice footwork outside of the area before unleashing a fierce left footed shot that was well saved by Modena keeper Nicholas Caglioni. And Sgrigna came close to opening the scoring moments later, but his header from Alessandro Parisi's cross was tipped over the bar.
The former Vicenza striker was having a great first half, and he turned provided for Torino's next opportunity. His fantastic left footed cross found strike partner Rolando Bianchi, but his header was off target. The form of Torino's captain is becoming a worry, as Toro's top scorer for the past two seasons has not scored since mid-October.
Ten minutes before half time, Torino took the lead with an early contender for goal of the season. Manuel Iori found Alen Stevanovic with an inch-perfect cross field pass, and the former Inter winger fired a magnificent curling shot into the top corner from 30 yards. Torino had chances before half time to extend their lead, especially through Simone Verdi who could have done better when well placed. Modena also had a chance before the break, but Angelo Ogbonna did well to block Davide Di Gennaro's shot.
Torino were in control of the second half without really creating any clear goalscoring opportunities until the 75th minute, when a mix up between Kamil Glik and Ferdinando Coppola resulted in Giuseppe Greco being brought down and a penalty being awarded. However, for some inexplicable reason, it was Coppola who sent off despite it being quite clear that it was the Polish defended who had committed the foul.
Greco picked himself off the floor to convert the penalty, as he sent Toro's substitute goalkeeper Davide Morello the wrong way. And incredibly, with five minutes remaining, the home side got a winning goal against Torino's ten men when Maurizio Ciaramitaro's scuffed shot somehow found its way into the bottom corner.
Torino will certainly be disappointed to lose their last match of 2011, especially after taking the lead. At half time in this match, Torino had a seven point lead at the top of the table, but it could now just be one point if Hellas Verona beat Varese on Sunday afternoon. That being said, Torino have had a fantastic start to the season, and are certainly on course to gain promotion in 2012.
