It wasn’t worth waiting five minutes for, never mind five months, but Manchester United had already done more than enough in Austria in May.
They advance to the business end of the Europa League in Cologne next week and a quarter-final meeting with Copenhagen.
Ole Gunnar Solskjaer’s side will go into the mini-tournament in Germany as favourites, even though there was little evidence to support that on a drab night at Old Trafford.

Ole Gunnar Solskjaer's team will go into the mini tournament in Germany as one of the heavy favourites to lift the trophy
A 5-0 lead from the first leg before lockdown turned this tie into the deadest of rubbers and gave Solskjaer the chance to make changes again. He has used 36 players in Europe this season, a record for the competition.
Once again, however, United’s strength in depth was found lacking. When people question the club’s pursuit of Jadon Sancho because they already have Mason Greenwood and Marcus Rashford in the wide positions, this is why.
On one flank, Juan Mata looked like a 32-year-old in need of game time. On the other, Dan James played like a man whose season has been petering out for some time. Elsewhere, United were sloppy in possession and lacked pace and creativity without their key players.

LASK defender Philipp Wiesinger stunned Man United by giving his side the lead with a long-range strike after the break
LASK deserved to take the lead when Philipp Wiesinger put them in front with an excellent finish 10 minutes after half-time, but Jesse Lingard equalised with his second goal in as many games.
