Gallagher spoke after David Coote was filmed on video criticizing Liverpool and their manager at the time, Jurgen Klopp.
Coote called Klopp “German c***” and Liverpool “s**t” in the video from a few years ago.
But Gallagher said, per The Mirror: "I refereed for 46 years, and most of my decisions are based on instinct; you have a knowledge of the laws of the game, the experience that you built up over the years.
"You see an incident and act instinctively, it's like driving a car, you see a red light, you don't think ‘change gear, brake, stop’. You just do it.
“I don't think any referee has any chance to think like that (biased against certain clubs), what I would say is that at the top level, the scrutiny is so intense - it's unbelievable.”
