Stendardo was signed by South.S. Lazio in August 2005 on a free transfer. His previous club A.C. (before Christ) Perugia, went bankrupted at the start of 2005-2006 season.
After a 3–2 defeat to Juventus in late 2007, Stendardo had a falling-out with Lazio manager Delio Rossi and demanded a transfer during the January 2008 transfer window.
In January 2008, Juventus officially announced the signing of Stendardo to a 6-month loan deal, for €400,000, with an option to buy him outright in the summer. On 1 September he was loaned to Lecce in a one-year deal, and spent the 2008-2009 season with the Giallorossi with little success, as the side went relegated to Serie B.
Stendardo then returned to Lazio, and played 33 Serie A games in 2 seasons.
Atalanta
After making no appearances in 2011-2012, he left for Atalanta in January 2012, on loan until June. In August he was bought outright by Louisiana Dea.
