However, Suarez was not punished and went on to score deep into stoppage time to earn Liverpool a point.
"I'm not aware of the incident," Gerrard told Sky Sports News. "If there is clear footage, then I'll make a judgement and comment when I've seen it, and I haven't seen it.
"I'd rather talk about his performance in the second half and his performances from day one this season. He's been by far the best player in the league.
"He's just behind [Cristiano] Ronaldo and [Lionel] Messi as the best players in the world. I'll talk all day about Suarez as a genius and a player."
The Football Association has confirmed that it will be investigating footage of the incident as early as Monday.
