Jose Mourinho appeared to criticise opposition manager Antonio Conte's conduct on the touchline after Sunday's game against Chelsea.
With that in mind it seemed only right we took a look at his own pitch-side antics, by looking at the Manchester United manager's behaviour during Wednesday's EFL Cup derby against Manchester City.
Mourinho spent the entire 90 minutes in the technical area.
The United boss' predecessor Louis van Gaal was often criticised for failing to appear on the touchline, but that is certainly not something that can be levelled at the Portuguese.
Not even his opposite number Pep Guardiola could match his stamina, with the City boss occasionally retreating to the bench.
For one often so animated, Mourinho was rather subdued by his standards, for the most part. He tended to react to incidents he did not like by throwing his arms up above his head, but only got angry on a couple of occasions.
He also had a notepad with him and, in the early stages especially, repeatedly crouched down to write something in it. Whatever he was writing down, it formed the basis of his instructions to Morgan Schneiderlin before he was sent on as a substitute.
He did celebrate when Juan Mata scored though, but in an understated way and was barking out instructions again within seconds.
Contact with opposition
Mourinho and Guardiola had a fierce rivalry during their time in Spain but have been fairly civil towards each other since they both arrived in Manchester in the summer.
Prior to kick-off they embraced and were all smiles, while their handshake at full-time was cordial. Mourinho also appeared to share a joke with City substitute Sergio Aguero as the pair made their way back to the dugout for the second half.
There were a handful of occasions when Mourinho let his frustration get the better of him.
In the first half he shouted in the direction of fourth official Lee Mason after a decision went against United but he soon backed down and offered his hand moments later. Mason later did his best to ignore arm-waving gestures from Mourinho suggesting he felt City should have been penalised for handball.
