Norwich City goalkeeper Angus Gunn shared the team's disappointment after the Canaries were unable to find an equaliser against the Millers.
When asked to sum up the performance, Gunn said: "Not good enough, we're really disappointed in the dressing room after that one.
"Especially after the first half, we didn't show enough, we got bullied and they scored two sloppy goals, preventable from us.
"I'm really disappointed and annoyed but there's nothing we can do now until Stoke at home."
The City stopper's start today means Gunn has now reached 100 appearances in a Norwich shirt across his two spells with the club.
"I didn't know I had reached 100 appearances, so that's a nice thing to have but I wish we could have finished it off with a win.
"I'm really proud to represent the club and hopefully there'll be more positive games to come than this one."
Gunn will be part of Steve Clarke's Scotland national team in the upcoming international break, where the Tartan Army will face Cyprus and England.
"Now it's a chance for some of the lads to go away and some of the lads to stay at the training ground working hard, getting fitter.
"I'm going up to Glasgow tomorrow and I'm looking forward to meeting up with the squad and getting some more minutes with the national team.
"It'll be two important games and hopefully we can get two more wins."
