Liverpool manager Jurgen Klopp was not afraid to take out his frustrations on Sunday evening.
The German aimed a dig at former referee Mike Dean, who is now a Sky Sports pundit.
Klopp spoke about how his team did not get a last minute penalty for a Jeremy Doku high challenge on Alexis Mac Allister in the last minute of their 1-1 draw with Manchester City.
He said of the incident: "His foot is right there and yeah he hit the ball but if the ball is not there, he kills him."
He said: "Did you employ Mike Dean, is he working for Sky? Congratulations, that's a great appointment by the way!
"He will find something and all the others as well. This is a penalty for all football people on the planet, it's a penalty.
"If you think it's not one, then maybe you're not a football person."
