Giggs has chalked up a staggering 745 appearances and scored 143 goals since his debut for United almost 17 years ago.
He has won a remarkable 15 major trophies with the club during that time, including the Champions League in 1999.
And Ferguson believes more glory will come the former Wales international's way if Giggs continues to manage his body carefully.
"Even at 34, we expect big things from him," added Ferguson. "Obviously, we don't play him in every game but that's natural for someone of that age.
"We want to play him in games that really matter to our club. The Champions League, to me, represents the biggest challenge in football.
"Footballers with real vision and real purpose in life always want to play in the biggest tournaments and Ryan has always reserved his best performances for the big occasions.
"When players are asked to be challenged in a big way, it is in European football.
"The great nights and atmosphere at Old Trafford can only happen because the right type of players are playing on that stage and Ryan has produced many great moments for us."
