Nottingham Forest legend Colin Barrett has told Jurgen Klopp to "shut up" after the Liverpool manager complained about fixture congestion.
Liverpool will face Forest in the FA Cup quarter-finals next Sunday, but before that they have games against Inter Milan, Brighton and Arsenal.
With that in mind, Klopp is calling for the re-introduction of five substitutes as they rival Manchester City for the Premier League title in their pursuit of a quadruple.
