Pep Guardiola was involved in a heated exchange with Mike Dean after a controversial moment on Sunday afternoon.
Manchester City are taking on Liverpool at Anfield in an all-star clash in the Premier League.
And they have not disappointed the many spectators across the world with many tipping the two titans to tussle it out for the title.
With the scores level at 1-1, James Milner was perhaps lucky to escape a second yellow card when he fouled Bernardo Silva after he skipped past Jordan Henderson.
On the touchline, Guardiola was absolutely incensed - demanding a booking in an animated fashion.

Working as a fourth official, Dean stared at the Catalan coach - clearly unamused - as the City manager continued his protests.
It led to the former Barcelona boss throwing his coat off in anger and it led to a booking from referee Paul Tierney.
To rub salt further in the wounds, Mohamed Salah would go on to put Liverpool into the lead with an exceptional strike.
After holding off Joao Cancelo, he danced around Silva before bamboozling Aymeric Laporte to strike past Ederson in spectacular fashion.
Guardiola was positively furious afterwards, though he had simmered down into his seat.
But his emotions got the better of him again when Kevin de Bruyne equalised when his effort was diverted past Alisson off Joel Matip's thigh.
The City manager screamed into the air with his mouth agape as the Anfield crowd watched on.
Pep Guardiola and Mike Dean had an incensed moment
Milner was brought off by Jurgen Klopp in the aftermath of the controversial decision.
Perhaps to avoid seeing the former Aston Villa star sent off, he put Joe Gomez on to help shore up his defence.
However, he could not stop City pushing for an equaliser as the match ended 2-2.
Sadio Mane had put Liverpool ahead earlier in the contest on the hour-mark after some fine work from Salah.
Phil Foden scored a fine strike of his own, clinically powering a shot past Alisson after some fine work from Silva.
The match means Chelsea go into the international break as Premier League leaders.
City stay behind Liverpool in third, trailing by a point and level with Manchester United on 14 points.
