Sir Alex Ferguson teamed up with former chief executive David Gill to help seal Juan Mata's transfer from Chelsea, according to the Daily Express.
The former manager has been closely watching his successor David Moyes since leaving the manager's post in the summer. Ferguson has frequently been seen at Manchester United games and has been happy to have his say on their up-and-down season thus far.
A return to the dugout looks far from likely for the legendary manager, but that doesn't mean Ferguson still can't dip his toes in to some of his old duties.
And it seems he did just that in order to help Moyes seal the record-breaking signing of Mata from Chelsea. Once Moyes had given the go-ahead on an approach, Ferguson teamed up with Gil in secret talks, approaching their large list of contacts to make the deal happen.
Manchester United could hardly afford another transfer failure after botched attempts to sign Cesc Fabregas from Barcelona and hijack Real Madrid's deal for Gareth Bale.
They also spent an extra £4.5m signing Marouane Fellaini because they moved after his release clause had expired.
So Ferguson and GIll helped their respective successors - Moyes and Ed Woodward - to seal the club record bid for Mata, delivering a world of experience when dealing with major transfers.
The Glazers have also commissioned further transfer moves for more marquee signings with players such as Mario Mandzukic and Diego Costa under consideration.
There is also considerable attention being paid to tying Wayne Rooney down to a new long-term contract.
