Molby, who led Kidderminster to a 2-1 victory at Yeovil on Boxing Day, warns Gerard Houllier to prepare well for the game at Huish Park.
"Yeovil are a strong, physical side and I am sure they will give Liverpool a game," said the big Dane.
"If Liverpool don't prepare properly for the game or go into it thinking it is going to be easy then they could be in for a shock."
