City have made an offer for the 23-year-old, believed to be around the ?5million mark, but Laudrup says his omission from the squad is not a sign that a deal has been agreed between the two clubs.
He said: "There are a lot of things going on around Scott and I spoke with him and we decided it was better for everyone that he did not participate at all in the game. We know things can move fast in this game but we will wait until Monday to see where things stand. We know it could go on until Friday evening."
The Dane added: "If he is still here after that he will be in the squad next Saturday, if he is not, he is not. There is a lot of interest in Scott. I really don't know if he will be here after Friday but everything is possible. It is possible he stays, it is possible he leaves."
Goals from Angel Rangel, Michu and Danny Graham secured a comfortable victory for Swansea, although West Ham were guilty of gifting their hosts two of those goals thanks to errors from Jussi Jaaskelainen and James Collins.
West Ham boss Sam Allardyce, meanwhile, readily admitted the first-half mistakes from Jaaskelainen and Wales international Collins had cost his side any chance of getting something out of the game.
"We have been punished severely for two very big errors by Jussi and James," he said.
"Mistakes by our two most experienced players, who have a huge amount of experience in this league, have cost us the game today.
"We could not overcome them and Swansea ran out comfortable winners.
"We have to take it on the chin and make sure we don't make those errors again as in this league you will be punished for them."
