This Red Samurai showed off his freestyle skill in front of players Radamel Falcao, Juan Mata and Marcos Rojo.
Manchester United posted a video of the masked ninja impressing the footballers with his nifty footwork before they showed off some tricks of their own.
The club has asked fans to record their own skills and post the videos using the #RedSamurai hashtag.
Remember, we want to see your freestyle skills. Tweet your videos using #RedSamurai and we'll share the best. #mufc
