Three goals up at half-time, the Foxes somehow managed to lose the bottom-of-the-table clash at Molineux.
"Any loss is tough to take but this one is very hard for me to accept and very hard to explain away.
"If you look at the games we've played so far you'd have to say we're a fantastic 45-minute team and the game seemed to hinge on them simply coming out for the second half.
"So maybe I've got to start questioning what I'm saying to my players because obviously they're not listening to me.
"I know my players and I know they work as hard as they possibly can so it's hard to be critical of them.
"I know I'm going to need them for a game next week.
"There's no more budget left for me to spend on new players so the one thing I'm not going to do is have a go.
"But I have got to apologise to the fans."
