In the 2012–13 season, De Rossi received less playing time and featured in just 25 matches. His manager Zdeněk Zeman was often critical of De Rossi's performances, and as a result he was used with less frequency. After Aurelio Andreazzoli's arrival, however, De Rossi started playing with more regularity, although he did not manage to score any goals.
