Although the now 74-year-old Ferguson, who retired as Manchester United's manager in 2013, has no desire to return to the dugout, Sunday People Sport understands he WOULD be prepared to take a hands-on role behind the scenes to help fellow club legend Giggs, currently Van Gaal's No 2, navigate the remainder of the season if the Welshman was given the reigns.
Van Gaal faces another crucial moment in his United career at Anfield on Sunday, with many believing he won't be able to carry on if his stars suffer a heavy defeat at arch-rivals Liverpool.
Since having a hand in the appointment of David Moyes once he decided to step down, Ferguson has effectively been excluded from any of the key strategic decisions taken by the club.
But he retains the respect and support of the American Glazer family who own he club.
If Giggs does take charge before the end of the season, as he did when Moyes was sacked in 2014, he would ask for Ferguson's help him in the closing months of the campaign - and possibly beyond.
Ferguson - who has refused offers to comment on United since he stepped down - wouldn't refuse that request, especially from one of his favourite former stars, although it's believed he wouldn't want a return to the dugout.
The Scot, who has carved out a lucrative sideline doing lecture tours on business management, is still a £2million-a-year senior United ambassador.
And he's been a regular in the Old Trafford directors' box this season, watching his former side struggle under Van Gaal's guidance.
