Reading boss Steve Coppell admitted he feared it would be one of those days for his team after Leroy Lita's first half opener was disallowed.
Lita put the Royals ahead against City only for the assistant referee to rule that the ball had gone out of play prior to the goal.
But Lita made amends with two goals inside 10 minutes in the second half as he hit the back of the net in the 79th and 89th minutes to hand his side a 2-0 victory on their visit to face Manchester City at Eastlands.
Coppell, who spent 33 days as City boss a decade ago, is refusing to get carried away though after his team climbed into the Premiership's top six following the result.
The Royals have now reached the 40-point mark, which should guarantee a place in the top flight next term but Coppell is not even contemplating what a place in Europe next season would be like.
"I am not really worried about artificial points targets being attained," he said.
"We have to try to finish as high as we can and forget about anything else.
"We are what we are - a team very much with the L-plates on. Sometimes you can find in situations like these, you do not know who you are playing against, so you are not afraid of it."
