Leicester City manager Marti Cifuentes spoke to BBC Radio Leicester following Saturday's 2-0 defeat by Blackburn Rovers.
"It was definitely a poor performance, there is no hiding from that," he said.
"There is more in this group of players, I'm sure, and we now need a reaction. I understand that we cannot keep waiting. I expect much more from them.
"When a club like Leicester is in the Championship, the expectation is that they are always at the top. And at the moment we are not achieving those standards.
"It's very hard as a manager to come into a place that I knew would be a difficult situation.
