Pep Guardiola wants to see fans return to football stadiums as soon as possible but only when Covid-19 is in retreat.
Manchester City will try to make it through to the quarter-finals of the Champions League on Friday night, taking a 2-1 lead over Real Madrid into the second leg.
But they'll have to cope with an empty Etihad Stadium, in contrast to the first leg back in February when 75,615 packed the Bernabeu prior to the pandemic.
The UK Government wishes to get at least some spectators back inside sporting arenas by October but this depends on the rate of coronavirus infection falling to safe levels.
And Guardiola said: 'I think all professionals, not just the manager, miss spectators. That is the reality but we have already adapted a little bit.
'It depends on the health if we are going to play with fans. When it is going to happen it needs to be secure for everyone.
'We want kids to go to school as soon as possible, that is maybe more important than people coming back to stadiums.'
Goals from Gabriel Jesus and Kevin de Bruyne gave City a crucial 2-1 advantage over Real in Madrid but Guardiola doesn't believe the first leg will have bearing on the return.
He said: 'It is a long time ago, the first leg. It is a different game. We knew that. We are at home without our people but we will try to do a good game.'
City are on course to play the winner of the tie between Juventus and Lyon in the quarter-finals if they complete the job against Real. Lyon lead the Italian champions 1-0 in the tie.
The Premier League side will be without record goalscorer Sergio Aguero on Friday as he continues his recovery from knee surgery but the Argentine could return for the final stages of the tournament, to be played in Lisbon.
Guardiola said: 'He is getting better. I spoke with the doctors and everything is like we thought but he is still in Barcelona so I don't know. Hopefully he can come back and start training with us but I don't know.'
