Mason Greenwood spared Manchester United's blushes with his first goal for the club as Ole Gunnar Solskjaer's youthful side edged past Astana 1-0 in the Europa League at Old Trafford
It took United, who made nine changes from the side that beat Leicester last weekend, until the 73rd minute to break the deadlock with Greenwood opening his account in fine style on just his second start for United
The 17-year-old showed exactly why , emphatically finishing into the bottom corner to ensure United, who also handed starts to Tahith Chong, Angel Gomes and Axel Tuanzebe, started their European campaign with a win

United, who named their youngest European line-up since 2012, started brightly and they were inches from taking the lead in the third minute when Fred's powerful strike clipped the top of the crossbar
Marcus Rashford could have had a hat-trick in the first-half but the England forward was denied on more than one occasion by Astana goalkeeper Nenad Eric
After the break United were on the front foot again but they could not make their dominance tell as neither Greenwood or Chong could turn in Marcus Rojo's teasing cross at the far post
Minutes later the ball fell kindly for Greenwood just outside the six-yard area but the youngster's shot was superbly blocked by the outstretched boot of Ivan Maevski as the frustration continued to build around Old Trafford
Solskjaer eventually turned to Jesse Lingard and Juan Mata in place of Chong and Gomes as an embarrassing result loomed, but it was Greenwood who saved the day for United 17 minutes from time
Creating space for himself in the penalty area, he powerfully struck the ball into the bottom corner in front of the Stretford end to hand United all three points, and you could sense the relief all around Old Trafford
 "When you don't score in the first half from four or five massive chances, you're always wondering if it's one of those nights that you're going to get punished for being sloppy
"But then again their keeper did well, he made some fantastic saves
 I didn't feel confident that we're going to win the game until the referee blew his whistle
"So, I don't think we played the last 10-15 minutes out well after we scored and that's something these boys need to learn as well
"Manchester United striker Marcus Rashford: "Me being in his shoes in the past, I know how he feels
 Even more important, that was the goal that won us the game, that's what everyone should be talking about
"He's been doing well since he joined the first team and there is 100 per cent more to come from him
 I'm sure he is excited and everyone else is excited as well
