"That could play into Leicester's hands but with their confidence shot to pieces and how they are playing, I can't see them getting anything. They are never going to get back to where they were last season, it's impossible.
"But they do need to rekindle the spirit they showed towards the end of the season before last when they were in a relegation battle.
"It clicked for them then and they got the results they needed to survive. It needs to happened again."
