Pep Guardiola has laid down the gauntlet to Manchester City's supporters, demanding that they show they want their team to take a place in the Champions League semi-finals.
Guardiola's side must overturn a 1-0 first-leg deficit against Tottenham Hotspur at the Etihad on Wednesday night in order to reach the last four.
City supporters have an uneasy relationship with the Champions League and boo the competition's pre-match anthem in protest against organisers Uefa.
Tickets for Wednesday night's game are also still available in a restricted sale.
And Guardiola made an impassioned plea to supporters to get behind the team, telling them he was "curious" to experience the atmosphere at the Etihad.
"Do it for the guys," he told City fans. "The last 20 months, [the players] are so proud with what they have done.
"They are human beings, they will have bad moments in the games and at that moment we need our supporters.
"At this stage, without supporters, we cannot go through. I'm expecting. I’m really curious to how our fans are going to react tomorrow. Really curious.”
The atmosphere for the win over title rivals Liverpool in early January was one of the best experienced at the Etihad in years.
Guardiola cited it as an example of what he wants to see from his supporters against Tottenham.
“The Liverpool game would be enough for me, a little bit better. We need it," he said.
"Sorry guys, I'm a failure in this competition but many times I played in the semi-final and quarter-finals, and every time I played away the atmosphere was really incredible.
"They support their local teams. We need it. Really, we need it.
"I want to see that they want to get to the semi finals. Not the players, the players no doubt after 20 months.
"I want to see my fans, our fans, that they really want the semi-finals. I want to see that tomorrow.”
