Guardiola has also been giving it a lot of thought. He has not been sleeping very well, as he has said, and has not been himself at times when talking to the media.

He has been talking to a lot of people about what is going on as he tries to work out the reasons for City’s demise. Some reasons he knows, others he still doesn’t.

What people perhaps do not realise is Guardiola hugely doubts himself and always has.

He will be thinking “I’m not going to be able to get us out of this” and needs the support of people close to him to push away those insecurities – and he has that.

He is protected by his people who are very aware, like he is, that there are a lot of people that want City to fail.

It has been a turbulent time for Guardiola. Remember those marks he had on his head after the 3-3 draw with Feyenoord in the Champions League?

He always scratches his head, it is a gesture of nervousness. Normally nothing happens but on that day one of his nails was far too sharp so, after talking to the players in the changing room where he scratched his head because of his usual agitated gesturing, he went to the news conference.

His right-hand man Manel Estiarte sent him photos in a message saying “what have you got on your head?”, but by the time Guardiola returned to the coaching room there was hardly anything there again.

He started that day with a cover on his nose after the same thing happened at the training ground the day before. Guardiola was having a footballing debate with Kyle Walker about positional stuff and marked his nose with that same nail.

There was also that remarkable news conference after the Manchester derby when he said “I don’t know what to do”.

That is partly true and partly not true.

Ignore the fact Guardiola suggested he was “not good enough”. He actually meant he was not good enough to resolve the situation with the group of players he has available and with all the other current difficulties.

There are obviously logical explanations for the crisis and the first one has been talked about many times – the absence of injured midfielder Rodri.

You know the game Jenga? When you take the wrong piece out, the whole tower collapses. That is what has happened here.

It is normal for teams to have an over-reliance on one player if he is the best in the world in his position. And you cannot calculate the consequences of an injury that rules someone like Rodri out for the season.

City are a team, like many modern ones, in which the holding midfielder is a key element to the construction.

So, when you take Rodri out, it is difficult to hold it together. There were Plan Bs – John Stones, Manuel Akanji, even Nathan Ake – but injuries struck.

The big injury list has been out of the ordinary and the busy calendar has also played a part in compounding the issues.

However, one factor even Guardiola cannot explain is the big uncharacteristic errors in almost every game from international players.

Why did Matheus Nunes make that challenge to give away the penalty against Manchester United? Jack Grealish is sent on at the end to keep the ball and cannot do that. There are errors from Walker and other defenders. These are some of the best players in the world.

Of course the players’ mindset is important, and confidence is diminishing. Wrong decisions get taken so there is almost panic on the pitch instead of calm.

There are also players badly out of form who are having to play because of injuries.

Walker is now unable to hide behind his pace, I’m not sure Kevin de Bruyne is ever getting back to the level he used to be at, Bernardo Silva and Ilkay Gundogan do not have time to rest, Grealish is not playing at his best.

Some of these players were only meant to be playing one game a week but, because of injuries, have played 12 games in 40 days. It all has a domino effect.

One consequence is that Erling Haaland isn’t getting the service to score. But the Norwegian still remains City’s top-scorer with 13. Defender Josko Gvardiol is next on the list with just four.

The way their form has been analysed inside the City camp is there have only been three games where they deserved to lose (Liverpool, Bournemouth and Aston Villa). But of course it is time to change the dynamic.
