The Dutchman came on as a substitute against Everton in the Premier League on Monday but failed to make any considerable impact, as United went down 1-0 at Goodison Park.
"I am excited myself about Robin van Persie," said Ferguson on United's official website. "He is a very good player.
"He brings a maturity to us up front. I am looking forward to him starring when he starts.
"The important thing for us is he brings something to the team. His goal record last year hopefully transmits itself to our goalscoring performances and give us more of a goal edge."
Ferguson went on to explain how Van Persie's addition to the United squad increases his attacking options.
"Wayne [Rooney] got 30 [goals] last season and he has been improving his goal total for the last few years," said the Scot. "We need that goal contribution from all the strikers.
"We know Chicharito (Javier Hernandez) is capable of scoring goals in a different way to Robin and Wayne.
"Danny Welbeck is also a different type of player. It does give us fantastic options. That is the biggest attraction to me."
United will host Fulham at Old Trafford in their second Premier League game of the season on Saturday.
