Hull boss Steve Bruce says Ryan Giggs is unlikely to be daunted at the prospect of leading Manchester United for the remainder of the season.
The 40-year-old will be in charge of team affairs for Saturday's game against Norwich following the sacking of David Moyes earlier this week.
The last five years of Bruce's Old Trafford career coincided with the start of Giggs first-team life at United.
Bruce says becoming a manager is no easy gig but believes his former team-mate will take it all in his stride.
He told Sky Sports News: "I wish him the best of luck. He's the most decorated player in the English game, and I doubt there will be anyone else who will win the number of medals he's got, but now he's in the hot seat, so good luck to him.
"Whether he enjoys it or not, that's the big thing. Make no mistake, when you pick your first team and do your first team talk, it's difficult and then you'll understand how difficult the job is.
"You then have to concentrate on the game and make changes. But the one thing that will never daunt him is the Man U thing - it's been there all his life.
"He's got round him people who understand the United way. And if he wins the next three or four games 4-0, there will be a clamour to give him the job full-time."
And another former United team-mate of Giggs, Ole Gunnar Solskjaer, believes he has what it takes to shine in the role.
The Cardiff boss said: "He is not one of those who always speaks every single day but when he speaks you listen. It has always been that way. He commands respect.
"He has all the attributes to become a top, top manager and, as a boy from Cardiff, he should do us favours now. The next two United games are important for us too (Norwich and Sunderland)."
Stoke manager Mark Hughes, another former United striker, expressed disquiet over the circumstances of Moyes' departure but went on to praise the appointment of Giggs.
He said: "It's probably the right appointment, the only appointment given the week that Manchester United have had.
"It makes total sense. The knowledge and understanding of the place that he has is invaluable for them at this moment in time."
