Manchester City boss Pep Guardiola believes they'll find out tonight how much their fans want to reach the Champions League semi-finals.
He's called on the home supporters to get behind the players as they look to overturn a 1-nil deficit in their last-eight tie with Tottenham.
Guardiola says his team will definitely be up for the occasion.
Liverpool take a 2-0 lead to Porto in the second leg of their quarter-final, with the winners set to face Barcelona in the last-four.
Reds' boss Jurgen Klopp insists his team will 'go to win' rather than try to defend their lead.
Kick-off in both games is at 8pm.
