The Australian international has signed a three-year contract, and the deal was confirmed by Torino director Stefano Antonelli.

The 27-year-old helped Parma avoid relegation last season, making 35 appearances for the Gialloblu.

Grella becomes Torino’s second signing of the summer after they completed a deal for Palermo captain Eugenio Corini earlier in the week.

Grella spent four seasons with Empoli before being signed by Parma in August 2004.

His previous clubs include Canberra Cosmos and Carlton in the Australian National Soccer League.
