The Academy graduate has made 75 appearances for the club so far and scored four goals across all competitions, including our Goal of the Season for 2018/19.
Andreas has previously spent two seasons on loan in Spain: the 2016/17 season at Granada and then the 2017/18 campaign with Valencia. Last term, he gained more experience with a temporary spell in Italy with Lazio.
Our former youth-team player returned to the club in the summer and performed well throughout pre-season.
Andreas netted a stunning goal in the friendly against Brentford at Old Trafford, highlighting his undoubted ability in the attacking third.
