With their 3-2 victory against Villarreal on Tuesday night, Liverpool booked their place in the Champions League final. With this, Jurgen Klopp became the first coach in men's football to coach his side to a FA Cup, League Cup and a Champions League final all in the same season.
Liverpool could win the quadruple, trumping Manchester United's Treble in 1999 in the process. It is the worst-case scenario for fans.
To compound fan misery, United fans will be hoping that Manchester City are the ones to deny a historic Liverpool clean sweep. This is how far United have fallen.
