Admittedly he's on the other side of the world playing for Japan against New Zealand, but the Kagawa defenders will undoubtedly use this display as further ammunition in their battle to get Kagawa a start at Old Trafford.
Within four minutes, the Japan playmaker had set-up his country's first goal before he then got on the scoresheet himself from the penalty spot before half-time.
New Zealand weren't offering up much opposition, but the first pass in particular was a perfect example of the kind of quality many Manchester United fans feel Kagawa can bring to the United starting eleven.
But Moyes has often left him on the bench, instead preferring to go with a combination of Antonio Valencia, Wayne Rooney, Adnan Januzaj, Ashley Young and Juan Mata in the attacking midfield positions this season.
A £17m purchase from Borussia Dortmund in the summer of 2012, many United fans had high hopes for Kagawa after glowing recommendations from Bundesliga watchers.
Unfortunately, for whatever reason, he's failed to live up to the hype.
After 50 minutes, Japan were 4-1 up on the All Whites.
