Maigari was quoted extensively by local media as saying that the Swede had turned down the offer of a new deal and former striker Samson Siasia had been offered the job.
But the NFF boss said that was not the situation: "At the moment, the situation is that Lagerback has asked for a few more days to conclude discussions with his lawyers and his family. Right now, he has not said yes or no. But he will get back to us in a few days."
Siasia, who has reportedly been named as the Swede's successor, confirmed meeting with NFF bosses, but said he was only made a conditional offer.
"I spoke to the NFF people and they told me that if Lagerback did not come back, they could give me the job. Right now, I cannot say much because nothing is finalised, yet."
