Giggs, 44, spent his entire playing career at Old Trafford and featured 963 times over the course of 24-years in the first-team.
He went on to serve as an assistant to David Moyes and Loius van Gaal, before assuming the role as the Wales national team coach.
And within the current debacle at his former club, the Red Devils legend feels there's no better man available for the current task at hand; to restore the glory days of the Premier League giants.
"Manchester United have got a fantastic manager already there," he said after naming the Wales squad for the UEFA Nations League.
"The club are going through a tough time but you've got to come through those tough times. I don't see where Manchester United go after Jose Mourinho. I think they've got the right man and they should stick with him.
"The club, the players and the fans should stick together."
Giggs went on to defend the outburst that saw the former three-time Premier League winner storm out the post-match press conference.
"I was at the game and I understand Jose's frustration because on another day United win that game," he said. "They didn't and then because of the way the game ended with the third goal, it looks worse than it was.
"You can only control what you can do. Manchester United have got a fantastic manager, a fantastic group of players and it is a fantastic club.
"They will come out of it hopefully sooner rather than later."
