Leicester City boss Nigel Pearson shrugged off the barracking of away fans after their FA Cup defeat at Aston Villa.
Leicester fans chanted 'what a load of rubbish' in the second half.
"People are entitled to their opinions, it doesn't matter what I think," boss Nigel Pearson said.
But with the Foxes out of the Cup and bottom of the Barclays Premier League the manager admitted they must improve.
He said: "We know we have a lot to do this season but what we have to do is find a way of being consistent.
"I never thought it would be easy but we're not making life easy for ourselves.
"We need mental resilience, absolutely. With the players' technical ability they are only able to put on show if they have the mental qualities to do that.
"It's been suggested that it is easier to prepare against the bigger sides but I do not know. We have found ourselves in losing positions far too often."
