"Let them keep talking. My conscience is clean. I respond on the pitch," he told Argentine radio.
However, the forward did concede that his attitude on the pitch must improve, but put it down to his "anxiety" to perform well for his team.
“As the years go by you realise what you have to correct. I am 25 and there are things I must improve, like my attitude on the pitch," he told the Daily Express.
“But that is how I have played since I was a kid. I try to correct it, but there are times when my anxiety makes me play that way.
“Everyone knows I gesture a lot, talk and protest, and those are things I must improve on.”
The pressure on Suarez to avoid bookings for simulation and dissent was increased on Thursday by Fabio Borini’s foot fracture, which leaves the Uruguay international as Liverpool’s only fit senior centre forward.
