Colback frustrated after Sunderland defeat
"The winning goal was difficult to take, especially after we'd just had a couple of chances ourselves," Colback said.
"I don't think it was a great game. Reading are fighting for their lives and it was always going to be tough.
"We had some opportunities - Alfie [N'Diaye] went through on the keeper, who then made a good save on Danny [Graham] - so to lose it after that was very disappointing."
