Sir Alex Ferugson expressed great interest in Vincent Kompany four years before he eventually signed for Manchester City.
A leaked 'discussion document' has surfaced online which shows Kompany as a 'transfer target' for Manchester United.
The piece of document was a detailed dossier of his United squad.
It was split into four categories; 'squad', 'excess', 'youth potential' and 'transfer targets/possibilities'.
One of Sir Alex's transfer possibilities was then-Anderlecht's Belgium defender, who transferred to cross-town rivals City in 2008.
Of course, Kompany has left City after 11 trophy-laden seasons and he ends on a high note following last season's incredible treble winning campaign.
They won the Premier League, FA Cup and League Cup in a remarkable season.
Kompany will go down as a City legend but it could have been so different if Sir Alex had snapped up his services back in 2004.
The Scot even went on a scouting mission to watch him in the flesh though another player grabbed his attention in the shape of Liam Miller.
"When I went to the Celtic vs. Anderlecht Champions League tie in Glasgow in November 2003, it was to watch the Belgian defender Vincent Kompany," he said.
"However, my attention soon gravitated to Celtic's energetic young midfielder, slight of stature but with an assured, calm way about him.
"What I witnessed was a player with a tremendous set of midfield fundamentals - his movement off the ball, his penetration of the Anderlecht midfield.
"I came away smitten by his performance, not least the timing of his runs. Leaving Parkhead I was totally determined to get Liam Miller to Manchester United."
Kompany, meanwhile, has returned to his boyhood club. The 33-year-old has been appointed Anderlecht's player-manager after signing a three-year deal.
City are also in discussion with Anderlecht about setting up an arrangement.
The link-up would see the Belgium club receive their players on loan.
