Federici was a key part of the Reading side that reached the FA Cup semi-finals in 2015, the first time Reading had reached the last four since 1927. In the semi-final, after making important saves throughout the match, Federici was at fault for Arsenal's extra-time winner from Alexis Sánchez as he allowed the shot to slip out of his hands and between his legs. Reading boss Steve Clarke defended and praised Federici after the match, saying they would not have even reached that stage without his efforts.
