Zdeněk Zeman
On 1 August 2012, Piris was loaned to Italian side Roma for a fee of €700,000, with the option of purchasing his rights at the end of the 2012–13 season for €4 million. He was virtually ever-present in the side under Zdeněk Zeman but, following the arrival of Aurelio Andreazzoli, he found playing time more difficult to come by, having to compete with Vasilis Torosidis.
