The Swiss international, 23, made only one appearance after moving to the Reebok Stadium from FC Zurich in 2007 - a serious injury curtailing his progress.

That appearance came in the club's 0-1 FA Cup defeat against Sheffield United in 2008, in which he came on as a second-half substitute.

During his season long spell with Torino, the club suffered relegation to Italy's second tier, Serie B.

He returned to the Reebok Stadium where he found players such as Fabrice Muamba and Mark Davies had overtaken him in the pecking order.

Bolton, meanwhile, have released Rob Sissons, Nathan Woole and James Sinclair.
