City and Chelsea are - allegedly - chasing the former Barcelona boss, along with Paris SG and Bayern Munich.
Ferguson has met Guardiola in New York several times since the former Spain midfielder announced he was taking a year off.
Fergie: “I spoke to Pep a while ago and he said he has no interest in getting back into management at the moment.
“His record is fantastic. The trophies that he won at Barcelona were quite exceptional and that is his CV – he wins trophies.
"Barcelona have always had that style and played attractive football. He increased that by putting a new work ethic into the players.
“They work extremely hard to get the ball back and if you combine that with their possession it makes a fantastic team."
