Celtic have been struggling to pay their players for quite some time, with Steve Komphela's men hoping the proposed sale of the team will alleviate their woes.
Despite their challenges, Phunya Sele Sele picked up Q-Innovation honours last night following a goalless draw with the Absa Premiership champions at Dr Molemela Stadium.
"It is overwhelming all the time coming here. It is unbelievable the passion that people have for this club and the passion they have for football," Mosimane said after the stalemate.
"It is really a sad case to find that this team has issues outside of football. The culture which is here is amazing and it is beautiful to have the opposing crowd, every time I'm at the stadium, calling me to the other side and singing for me.
"You are never going to get that [elsewhere]. It is more than football to be honest."
Meanwhile, Mosimane says Sundowns' finishing let them down in the Free State.
"The game itself, I think we controlled it. We bossed the midfield and got our passing right, but we lacked a little bit of X factor up front to kill the game.
"We got chances. But possession football doesn't win you games, we have to score."
The Brazilians, in seventh place on the table with 10 points from six games, next host log leaders Bidvest Wits at Lucas Moripe Stadium on Sunday (15h30).
