Josh Murphy admitted Norwich City were contributors to their own undoing after their 4-2 defeat to Aston Villa at Villa Park.
City twice got themselves back in the match at 2-1 and 3-2 down but Villa eventually prevailed, thanks largely to a hat-trick from Conor Hourihane.
Speaking to the media after the match, Murphy said: “We were good in spells but just weren’t good enough throughout the whole game. Villa probably deserved the win.
“It’s a hard one to take for us really. We get ourselves back in the game and we just let ourselves down a couple of minutes later and it was 3-1.
“Then we got back in the game again and let ourselves down again. It’s disappointing for everyone because it’s just sloppy mistakes and we’ve got to take that out of our game.
“We did it last season and we don’t want to carry it on into this season. We need to up it a little bit.”
Murphy said that City’s first half display ultimately left them with too much to do going into the second 45.
“Especially coming to Villa Park, we gave ourselves a mountain to climb,” he added. “We started climbing that mountain and then all of a sudden we fell back down.
“Changes are going to have to be made. We need to toughen up because it was just too easy for Villa today.”
