The 40-year-old midfielder was put in charge on Tuesday when David Moyes reign ended after 10 months with the defending champions in seventh place in the Premier League.
Speaking publicly for the first time since his temporary appointment, Giggs provided an insight into what he has told the squad ahead of Saturdays match against Norwich at Old Trafford.
I trust you and I know what youre capable of and go out there and show it on Saturday and give the fans something to shout about, Giggs said Friday. Entertain them, score goals, make tackles, play with speed, play with tempo.
Giggs is only expected to manage the team for the remaining four matches of the season before a more experienced successor to Moyes is appointed.
It has been a difficult week for the club and its been a bit of a whirlwind week for me but one Ive enjoyed, Giggs said. It has been different, chaotic and Ive been getting a little taste.
Giggs came through the youth ranks at Old Trafford and was part of the famed Class of 92 youth team that helped contribute to so much of the clubs success.
Ive had to take a bit of stick (from the players), Giggs said. Things like, Where are you going to park What do we call you
The players have been great and the reaction in training has been sharp. Ive just tried to make things relaxed and for everyone to enjoy themselves ... lets have a good end to what has been a frustrating and disappointing season.
The clubs most decorated player, who has made 962 appearances, is still in the squad and could pick himself to play against Norwich.
Ive just given myself a five-year contract, Giggs joked. I havent done much this week but am still involved as a player as well.
Giggs is being assisted by former teammates Phil Neville, Nicky Butt and Paul Scholes as he tries to stabilise a team in turmoil.
Its the proudest moment of my life, Giggs said. Ive supported Manchester United all my life. Im proud, happy, a little nervous but just like I am as a player I cant wait for the game on Saturday.
