The Bulgarian striker looks set to make his debut against Liverpool on Saturday, following his £32million move from Tottenham to Old Trafford on transfer deadline day.
“Berbatov is a Manchester United-type player,” said Giggs.
“He has that physique and stature because he is over six foot, so he offers something a little bit different to Wayne Rooney or Carlos Tevez. For a big man he has a superb touch.
“But he also has a big personality, the personality you need to be a success at Manchester United.”
He continued: “I am glad Dimitar is on the same side as me.
“I have seen his ability at first hand when he played against us for Tottenham.
“I am sure he will be an excellent signing.”
