The Argentine winger has made a big impact since moving to Old Trafford from Real Madrid in the summer, scoring three goals in six games for the Red Devils.
Di Maria has earned plenty of admirers during his brief career with United, and Giggs admits that the 26-year-old is the type of player that excites him.
"You don't need to do a lot with him," he told the Manchester Evening News. "He's that sort of player, he's a free spirit. He will take you from box to box really quickly and he will create and score goals. He gets bums off seats and he excites me. He's the kind of player you love to watch."
United return to Premier League action on Monday night when they face West Bromwich Albion at The Hawthorns.
