Craig Brown admits he is being a "bit selfish" in quitting Motherwell for a "better job" at Aberdeen but defended his right to change his mind.
Brown, 70, is in negotiations with the Dons after resigning as Motherwell manager on Thursday night. The former Scotland head coach reaffirmed his commitment to the Fir Park club on Wednesday following an initial approach from Aberdeen chairman Stewart Milne, but he performed a dramatic U-turn to leave Motherwell "surprised and disappointed".
Brown told BBC Scotland: "It's being a bit selfish but, when someone offers you a better job, I think it's understandable that we would be tempted."
He added: "Impulsively, we said no because of the fantastic response from the staff, players and fans at Motherwell.
"But when asked to reconsider, we did. And I believe everyone has a right to change their mind."
Brown has swapped the challenge of securing Motherwell's fourth successive European adventure for an immediate fight at the bottom of the SPL.
But he said: "We know there are high expectations in Aberdeen and we have high expectations for every team we have anything to do with. We're not magicians, we're not saying we're going to do this or that, we're just going to work conscientiously and diligently."
Motherwell have reported Aberdeen to the SPL alleging they have broken rules by tempting their management team away, although the fact the pair were not under contract could hamper their case.
In the meantime, chairman John Boyle made a public appeal to Aberdeen and his departed management team to delay an appointment until after the two teams meet at Pittodrie.
"I think that it would be a sporting gesture for Aberdeen, Craig and Archie to wait until we play them a week on Saturday before taking up their new position," Boyle said. "By doing that it would help Motherwell and we would feel that things are being done in a slightly better manner than they have been in the last couple of days."
