The Argentine striker's future is uncertain, having left AC Milan and snubbing the prospect of a return to Catania, allowing the newly-promoted side to take a look at him
After just one goal in eight appearances for the Rossoneri and the re-emergence of Antonio Cassano, the San Siro outfit decided against keeping the 28-year-old beyond the end of his temporary arrangement.
Lopez, who also holds an Italian passport, has made it clear that he does not see his future at current club Catania, and Torino are the latest team to have reportedly added the forward to their wishlist.
However, the Granata will have to beat off competition for Lopez's signature, with Fiorentina among others also in the running.
It would represent something of a coup for Torino, who will play in Italy's top tier for the first time in three years following their promotion from Serie B last term.
