Firstly, let’s deal with the reality of where Amorim finds himself now.

He was joking before the game when he said a Sporting victory over City would make United feel another Sir Alex Ferguson was arriving.

There was a huge amount of added interest in the game in Manchester. Those of a United persuasion, fans and club officials alike, were delighted with what they saw. To some, it made a mockery of City’s private insistence that Amorim was not a name on their wish list for when Pep Guardiola eventually leaves.

But nobody, Amorim said, should read too much into events at the Jose Alvalade Stadium.

“I already said previously you cannot transport one reality into another,” he said. “At Manchester United you cannot play exactly like this. You cannot play so defensively and so there we will have to adapt. Clearly it is really difficult to beat this team and to beat Pep Guardiola. And he is not a worse manager than me.

“It will be a completely different world, a different team, we won’t have that much time to train and we will begin from a different starting point. People can make their own judgements but I say to the people of Manchester that this was a one-off.”

Amorim’s observations about his defence are worth further examination.

The most obvious difference being widely analysed is that Amorim plays three central defenders.

Against City, that turned into a back five for long stretches of the game.

Yet that is one of the attractions. Inside United they believe labelling Amorim as someone who plays with three central defenders is too simplistic.

How that shows itself can change, it is argued. This could be through inverted full-backs, more orthodox wing-backs – which is what Geovany Quenda and goalscorer Maximiliano Araujo tried to be when they weren’t being pushed back – or central defenders stepping forward into midfield areas.

In front of them are two sitting midfielders, beyond that two narrow forwards and, up top, the excellent Viktor Gyokeres.

If Amorim sticks to the formation, does he have the personnel to make it effective?

If not, will he have to compromise to the extent Erik ten Hag did, where his eventual team bore no relation to the style he was supposed to be bringing with him from Ajax.
