Manchester United boss Ole Gunnar Solskjaer has no doubts about the potential of Mason Greenwood.
Solskjaer says the teenage striker will face Europa League opponents Astana.
The manager stated: "He's still very young but he's maturing and he's developed so much since I came in. The kid who just wanted to play with his mates in the U18s and now he's knocking on the door wanting to play more.
"His appetite for football is growing I don't want to put too much pressure apart from go out there and enjoy yourself and work hard. He's one of the best finishers I have seen go out at Old Trafford and enjoy it. Eleven Astana players living the dream tomorrow and I want it to be memorable for all our players as well and Mason is one of those."
