Hull City head coach Ruben Selles spoke to BBC Radio Humberside after his side was beaten 1-0 by Derby County to drop into the relegation places.
"The entire game changed when we conceded that goal and they managed the time at the end," he said.
"It was that final pass or the finishing action which we lacked. I don't think they were at any moment threatening us, we limited them to two shots and paid the price for not defending that set-piece well.
"I don't think our final product was good enough but I think we invested enough to get something from the game today.
