The veteran striker has made his mind up to quit playing come May but the Leicester boss feels he still has a lot to offer.
"I think Les is enjoying his football. He certainly gives me that impression," he said.
"Footballers know when it is time to call it a day but looking at Les I don't see why he can't play on.
"He will make that decision himself. Your body will tell you when it is time. But I hope Les continues."
