He was recalled for the enthralling Capital One Cup tie with Arsenal as the Gunners came from behind to win 7-5 and came back into the McDermott's league side following an injury to first-choice Alex McCarthy last weekend.
Federici, 27, shipped 14 goals in his four previous outings this season and was delighted to keep Norwich at bay.
"It is good to be back, it has been a tough time for me at the minute but it is good to be back in the team and the boys worked really hard today, defensively we were very solid and deserved a clean sheet," he told Reading FC Player.
"It was a good test, they are a good team and as I said our boys were solid which we have been lacking in the last few games in particular so it was nice for everyone to get a clean sheet.
"It is a good feeling being back in the team and a good feeling coming off with a clean sheet."
