The International Olympic Committee will vote Wednesday to decide whether London, Paris, Madrid, New York or Moscow will host the Games in 2012.
In the second part of our series giving an insider's view from each city, we move on to Madrid.
Alejandro Delmas, chief reporter at Madrid sports daily As, sums up the mood in the Spanish capital.
What's the atmosphere like in Madrid ahead of the vote?
People are excited, but they are not exactly optimistic about the outcome.
The IOC's evaluation report said Paris and London both had high-quality bids, and only that Madrid's was good quality.
Madrid is going to fight until the very end, but we don't know if it's going to be good enough.
So is Madrid's bid weaker now than before its evaluation?
I don't actually think the evaluation report is going to be a decisive factor.
I think the outcome will be decided at the last moment in Singapore.
What messages will the Madrid team try to get across?
The bid team will say that the city is completely ready to stage the Games, that a big majority of Spaniards back the bid, and that there is strong government support.
But they will also have to be prepared to answer questions about the Basque separatist security threat.
Who will be in Madrid's bid delegation in Singapore?
Real Madrid striker Raul, basketball player Pau Gasol, cycling legend Miguel Indurain and tennis player Arantxa Sanchez Vicario are on the list of sporting ambassadors.
There will also be members of the Spanish royal family, like Queen Sofia.
How do you think the vote will go?
I think Moscow will lose in the first round and New York in the second.
I expect there to be a close fight between London and Madrid to take on Paris in the final round, but I think the only winner is Paris.
Since the very beginning, I felt Paris was the strongest bid, because of its history, the fact it has bid twice before, hotel capacity and a lot of other things.
Will Madrid bid again if it does not win this time?
I think it will. There has been good public support for the bid, so why not?
