Manchester City will hope a sell-out crowd can roar them to victory in their crunch Champions League clash with Paris St Germain.
On Monday City sold the last of the 53,000 tickets they made available for Tuesday's quarter-final second leg against the French champions, guaranteeing a club record European attendance for the now eagerly-anticipated contest.
Last week's thrilling 2-2 draw at the Parc des Princes prompted a surge in interest in the match after previously sluggish sales. Supporter frustration at prices and fans' well-known apathy towards the competition and organisers UEFA were all factors in the slow uptake.
But now with City having a realistic chance of reaching the semi-finals for the first time, excitement has built and manager Manuel Pellegrini recognises the importance of having the fans onside.
The Chilean said: "We will have a full capacity here. The fans, for different reasons, have not been involved 100 per cent in this competition but as we continue further they will do it. They know this is a very important achievement for the club."
Pellegrini, however, is happy for supporters to carry on booing during the playing of the competition's anthem before kick-off. City fans have done this since last season as a means of airing grievances with UEFA but it has been suggested that, on such a critical occasion, it could set the wrong tone.
But Pellegrini said: "It depends if you are superstitious or not. If you are superstitious - we continue winning when they boo the anthem!"
Pellegrini was forced to give up on hopes of Vincent Kompany taking the field against PSG,
The influential captain and defender has made steady progress in his recovery from the calf injury he suffered last month but it seems the game has come too soon.
"Vincent Kompany is not 100 per cent," Pellegrini conceded at his pre-match press conference, despite allowing the Belgian to play a part in a training session made open to the media.
Asked if that meant he could still play, Pellegrini said: "No, it is not possible."
There was some good news in that Kompany's fellow centre-back Nicolas Otamendi, who sat out that session, did overcome an ankle scare and Pellegrini maintains faith in the Argentinian's partnership with Eliaquim Mangala.
He said: "I am absolutely confident because with this defence we played a lot of games here in the Premier League and in the Champions League and if we are in this stage it is because we have good defenders."
To progress, City will need to keep the prolific Zlatan Ibrahimovic quiet.
The Sweden international had mixed fortunes in the first leg, missing a penalty and another good chance as well as scoring and hitting the bar.
And PSG boss Laurent Blanc has warned City that the striker is keen to make amends for the missed opportunities in Paris.
Blanc said of the 34-year-old, who has been linked with Manchester United: "He wants to show something else, he wants to be more clinical in front of goal. If we create as many chances as the first leg, I think his conversion rate will be a lot higher."
