Ferguson is convinced the midfielder will help with the goals tally as well.
Ferguson said: "Shinji was fantastic on Monday, he played very well.
"He is a terrific pro, a good footballer, good with two feet, good balance and we're very happy with him.
"His goalscoring record is better than most players in that position. His last two years at Dortmund showed that.
"I think that will come for us. He will also create chances as he did on Monday. That shows he has the vision and passing ability to open up defences."
