It capped a fine week for the attacking midfielder, who on Thursday followed in the footsteps Paul Scholes and Ryan Giggs and won United's Youth Team Player of Year award.
Against Palace on Sunday he became the club's youngest player since Duncan Edwards and the first born after 2000 to make his United debut.
After the match he told MUTV: "Obviously, it's a dream come true. I've been here since the age of six working my way up, and it's what everyone dreams about.
"I just want to thank the manager for putting me on the bench and playing me today, and all the staff back at the club and everyone who has helped me.
"I'm from Manchester, Salford and it's literally down the road. It's just unbelievable."
