For a very brief period of time it looked as if Manchester United were about to pull off the unthinkable.
Their counter-attacking game-plan paid off around the hour mark when a cross from Antonio Valencia landed kindly at the left foot of left-back Patrice Evra - who fired in his first Champions League goal in seven years.
It was a magnificent goal, a tremendous moment - and one capable of winning the tie.
When Chelsea scored their winner against Paris Saint-Germain on Tuesday night Jose Mourinho ignored protocol and charged down the touchline to tell his players where to play for the rest of the game.
Moyes didn’t manage to do the same thing - that is not his style, and 22 seconds later, a still buzzing Manchester United let it slip through their fingers.
Evra, seemingly replaying the goal in his head, lost Mario Mandzukic at the far-post who tucked away an equalising header.
Thomas Muller and Arjen Robben did the rest - as the game-plan collapsed as soon as it went into action.
In all seriousness United can be proud of their display.
They took Bayern Munich - the best team in world football by far - to the very brink, pushing them all the way.
But it is still hard not to think of what might have been should they have held onto that 1-0 lead till later in the game.
One man who is also struggling to come to terms with the way they threw away a 1-0 lead is Gary Neville.
The former Manchester United defender and Sky TV pundit was at the Allianz Arena - and has just got back home after an early flight this morning.
He reportedly leapt from his seat in celebration when Evra smashed home that tremendous half volley - but we doubt he even managed to sit down before Mandzukic had levelled things.
And he has taken to Twitter to reiterate his disbelief and shock that his beloved United could not hold on to their lead for more than 20 seconds.
Morning,back home.Still can't believe we conceded 20 seconds after going one up. The plan that could have won the game fell apart thereafter— Gary Neville (@GNev2) April 10, 2014
