The Red Devils failed to finish in the top four of the Premier League table last season and are playing in the Europa League this campaign.
United got the better of Astana 1-0 at Old Trafford on Thursday evening to kick off their Group L campaign on style.
Mason Greenwood scored the only goal of the match in the 73rd minute when he found the net with a clever finish in front of the Stretford End.
Ole Gunnar Solskjaer’s side were the better team in the game, with Fred hitting the Astana crossbar from 25 yards, and England international striker Marcus Rashford had a number of chances to find the net himself.
