Kagawa, who will seal his move to Old Trafford if he passes a medical and obtains a work permit, often plays on the left wing for his country but is most at home in midfield, playing ‘in the hole’.
"I know he can play on the wing but I’ve only ever seen him play through the middle, behind the front man," Irwin added. "In that position he looks a talented player who can create chances for others but also scores goals.
"His record at Dortmund was impressive and they won two leagues in a row, the Double last season, so he must have been doing something right."
