He told the Swansea official website
“We knew exactly what to expect when we came here
“When you play at the Madjeski Stadium and you concede from the first shot on target, and another two goals from three shots on target, your concentration levels are going to give the game and points to Reading.
“Our defending in those situations was not good enough for our standards and in the first-half we didn’t show the levels we were capable of.
“Today we created our own problems and our concentration levels weren’t good enough.
“The boys were hurt,” added Roberto. “They want to go into every game and try to win it and we got a good reaction at half-time.
“I don’t think that many teams are going to come to the Madjeski and get 10 corners and hit the crossbar which is what we got in the second-half.
“We are disappointed because we lost away from home, we just have to learn a few lessons and we have a great opportunity on Tuesday (against Preston) to put it right.”
