Some people moaned about his position, but plenty of us here said he would be capable from out wide with the right players around him and with the right instructions.
There is night and day difference when he is playing with the likes of Mata, Januzaj and Hernandez to the Valencia, Young and Rooney at number 10. Why did he still seem capable last night? Well, simply because our standards changed for the night. It was pretty typical of his early performances in the season - picking up the ball, playing the right pass, keeping it in tight situations but that generally isn't enough for a United team.
When Rooney is at number 10 and Kagawa is wide they find themselves playing in the same area, getting in eachothers way. When Rooneys at number 10 is when we've seen the best link up play from the two - Leverkusen, Norwich.
He's a fantastic player.. and if you play players who are similarly minded and technically sound he'll be more influential - that is true of any player, including Mata.
