The iconic Italian has long held a standing as the finest goalkeeper in world football.
That reputation once made him the costliest custodian of all-time, with Juventus breaking the bank to lure him away from Serie A rivals Parma in 2001.
Another chance to head for the Premier League presented itself following the arrival of Sheikh Mansour’s riches at City, but once again Buffon opted against making a fresh start outside of his homeland.
The 41-year-old finally left Italy last summer after 17 years with Juve, but has told BT Sport of the interest he has attracted from Manchester: “When I was a boy playing for Parma, Ferguson tracked me closely for two or three years, and he'd always send scouts to watch me.
“At the time, Parma was my world and I didn't feel like leaving.
“I later had a very big offer from Manchester City, when they started to build the team and become the most important side in Europe.
“They wanted me to be the first signing, but I stayed at Juve.”
Buffon is currently readying himself for a meeting with United in the last-16 of the Champions League on Wednesday.
PSG lead that two-legged tie 2-0 heading into a return date at Parc des Princes.
Kylian Mbappe was among their goalscorers at Old Trafford and continues to be showered with praise during a remarkable run which has made him a World Cup winner and global superstar.
Buffon has saluted his potential in the past, while current boss Thomas Tuchel believes the 20-year-old can go on to achieve anything he sets his mind to.
The PSG manager told BT Sport: “Well the guy is hungry, and he is a big personality, really big.
“So this is not always easy, because the big personality is challenging for me as a coach. At the same time he is a really nice guy.
“It is important he has this personality to challenge me, and everyone around him, because he has the hunger to be really as special player in history.”
