Emiliano Moretti's 94th minute winner gave Torino their first win against Inter at the San Siro since 1988 on Sunday afternoon.
Giampiero Ventura made just the one change from the team who beat Cesena last weekend, and that was an enforced one, as the suspended Bruno Peres was replaced by Cristian Molinaro.
The first chance of the game fell to Fredy Guarin but the Colombian midfielder blazed his shot over the bar. Mauro Icardi forced Daniele Padelli into making a good save, whilst Joel Obi also fired wide of the target as the home side were limited to half chances.
Despite the home side dominating possession, Toro did look dangerous on the counter attack and Josef Martinez should have done better with a free header from a corner. The Granata were creating more and more as the game wore on, and both Cristian Molinaro and Fabio Quagliarella had late chances to earn all three points for Torino.
However, with the final kick of the game Torino did win it, as Omar El Kaddouri's corner was flicked on by substitute Maxi Lopez and experienced defender Emiliano Moretti got the final touch to earn the Granata a memorable victory.
This was a perfect away performance from Toro who remained solid at the back and for once took the chance that they were presented with in the latter stages. This victory was the first time Torino have beaten one of the established 'big clubs' in Serie A since returning to the top division three seasons ago.
