Agliardi signed for Palermo in January 2006, in a swap deal with Nicola Santoni (50% registration rights), and quickly became a first team regular.

On 17 September 2006, Agliardi and teammate David Di Michele combined to lift the Rosanero to a 2–1 victory over Lazio in Rome.

The result elevated Palermo to second place in Serie A, behind Lazio's city rivals and stadium-mates Roma on goal difference, with a 100% record.

Having made no appearances until the first part of the following season, Agliardi signed a loan deal with Serie B side Cesena on 31 January 2014.
